In our fourth SciArt Profile we meet Priyanka Oberoi, an illustrator, artist and photographer whose work often features scientific themes.
Priyanka with a wall of her art.
Where are you originally from and what do you work on now?
Originally I am from India, and am an illustrator and photographer by profession. After spending five years studying art in the College of Art in New Delhi and National Institute of Design in Paldi I started my career as a staff photographer for the magazine ‘Sports Illustrated’ in New Delhi, India. From there I moved on to freelancing as an illustrator and photographer full time. This gave be creative freedom to explore and time to increase my skill set. Studio pottery and wall murals are some of the few skills that I added to my portfolio. I started making scientific illustrations 4 years ago in Germany and currently continue the same in Brussels with my husband and five month old baby boy.
When did science first come in to your life?
I studied science and math in school about fifteen years ago. Deriving physics equations and finding the square root from a hypotenuse taught me that I was better suited for something else. While being an artist was never a childhood dream, it definitely became so after school, and I feel extremely fortunate to have found my forte in art.
Science came back in my life when a few scientist friends asked for some drawings. What started with scientific illustrations for journal papers went on to posters and merchandise for conferences, journal covers, gifs explaining various scientific concepts, lab wall art and more. The scope of scientific communication has really caught my imagination.
Who are your artistic influences?
The impressionists with their bold and confident brush strokes have always left me in awe, and Monet, Manet, Van Gogh and Surat adorn my home walls. The Indian artist from Goa Mario Miranda is someone I look up to for inspiration for my pen and inks. The pop colours in Andy Warhol’s screen prints gives me confidence to go crazy with my colour palettes.
What do you think of the relationship between science and art?
I am not a scientist, but the process of creating art certainly has an impact on scientific process. With art, one needs to distil an idea into a single, coherent visual representation. For instance, when I work with client to create a cover art or graphical abstract, a lot of thought goes into which elements faithfully represent the finding, not just for the author’s peers but for the broader audience. This certainly helps streamline scientific thinking. In-fact, I would suggest scientists create graphical abstracts of their work or progress, as it would help with understanding the major focus of the work and improving the planning of experiments.
“With art, one needs to distil an idea into a single, coherent visual representation”
How do you make your art?
Pen and inks are my specialty when it comes to illustrations. While I make most of my scientific illustrations digitally the comfort of the simple pen and paper are undeniable.
Be it a commissioned work of art or an idea that I want to bring to life, I always start with my little sketch book. I start by writing key words of a particular project, and if the client has any specific requirements then I note them down too, but if not I start with my favourite, a blank canvas. Then comes the mood board: this generates the basic feel of the artwork which includes the colour palette, sketch style, canvas shape and many such details. This gives the client an idea of the route I will take for the project. With these approvals I start with the artwork. Rough sketches start to adorn my sketch book. Some concepts take days to formulate while some just click instantly. These steps give me a clear passage into my final work of art.
I work on a variety of techniques. Sometimes if the requirement demands a painterly quality that I cannot achieve via digital platforms I go back to the traditional canvas or paper with high resolution scans. The bottom line is that the process is super intoxicating and so when one project comes to an end I cannot wait to begin the next!
What are you thinking of working on next?
I am currently working on a board game for the Deutsch museum in Munich – acompletely new challenge with its new set of rules.
Also filling up my sketch book pages is a self initiated project called ‘Danio & Rerio’. A weekly comic strip that I recently started on twitter that embarks on the adventures of two zebrafish and their stints with various fun science experiments.
Apart from commissioned works of art I conduct team building and exploratory workshops. One such workshop includes traditional wooden blocks that I got made in India. These wooden blocks are science themed with a twist used for block printing on bags, t-shirts and pretty much any surface. These workshops are open to any lab that want some reclamation time. This inexpensive activity is fun and refreshes all the members of a lab without planning a formal retreat. One set of workshops are going to be offered to an international school in Brussels for their extra curricular spring and possibly summer sessions.

We, Jose Casal and Peter Lawrence, have an opportunity to hire a suitably qualified research assistant to help us for 6 months starting anytime from March Ist. Unfortunately we do not yet know if the job could be extended further than that, but if there is anyone who knows flies, is skilled with the confocal microscope and would like to join us briefly we can pay them at the going rate from the remnant of our current grant until the money runs out.
We are in the Zoology Department of the University of Cambridge and work on planar cell polarity in Drosophila
As astronomers look up to the sky to analyze the infinite universe, developmental biologists look at life unfolding, revealing itself under the light of the microscope. Stars above us, embryos below, we wonder about the possible worlds hindered from our sight. These reflections took place at “The Marine Biology Laboratory Practical Course in Developmental Biology – Quintay 2020” in Chile, where a total of 18 students from 9 different countries (Argentina, Brazil, Chile, Colombia, Ecuador, India, Mexico, Puerto Rico and Uruguay) met, fascinated with the broad diversity of animals, range of experimental techniques, and the huge quality of faculty available in this course.
Despite the fact that most of us were working with one of a small number of “model organisms”, we had the unusual chance to observe, describe and perform experiments with flatworms, sea urchins, fruit flies, Zebrafish, African frogs, and chicken embryos. It was an intense 2 week-practical and theoretical course at the facilities of the Quintay Marine Research Center (CIMARQ) of the Andres Bello University. This immersive experience right next to the Pacific seashore of Chile, together with a remarkable array of experts in different fields of developmental biology in a friendly environment, encouraged us to explore some of the frontiers and unanswered questions in developmental biology.
Students at The MBL Practical Course in Developmental Biology in Quintay Marine Research Center (CIMARQ) in 2020.
The course began with the Drosophila module, coordinated by Profs. Nipam Patel (MBL, USA) and John Ewer (University of Valparaiso, Chile). We were introduced to the basic aspects of invertebrate embryogenesis, genetics, and the powerful impact of the Drosophila model in Developmental Biology. Nipam was a very engaging lecturer, transmitting us the beauty of visualizing embryos under a confocal microscope, and giving us the most useful advice for nice immunostainings: “You just need to Wash! Wash! Wash! …and have faith”. We got stunning expression patterns of Hox genes in Drosophila embryos that will become part of a joint publication with results from previous versions of this course. Next, Nipam introduced us to Evo-Devo, the possibility of exploring evolution through the lens of development, by analyzing the gene regulatory networks that establish the anterior-posterior axis of the crustacean Parhyale hawaiensis in comparison to Drosophila.
In sea urchin module, directed by the Prof. David McClay (Duke University, USA) or Uncle Dave as he would say, we took advantage of the CIMARQ-Quintay red sea urchin facility, learning some of the classical experiments of early embryogenesis and the morphogenetic events occurring during sea urchin gastrulation. Dave provoked us with inspiring discussions about developmental biology, and enchanted us with his passion earned through his many years in this field. His lectures about how sea urchin embryo development has been understood were like hearing a nine year old kid telling you about his favorite Christmas presents.
We continued with Prof. Cecilia Moens (University of Washington, USA), who engaged us with an inspiring talk about the early development of the zebrafish brain, and then guided us through a debate about employing gene editing tools such as CRISPR/Cas9 for dissecting early developmental processes, not only in Zebrafish but in almost all research organisms present in the course. This discussion was insightful since nowadays we have a vast array of tools for manipulating gene expression at our fingertips. We were able to compare the advantages and limitations of each one, highlighting the importance of conducting the proper experimental controls.
In the planarian module, Prof. Alejandro Sanchez-Alvarado (Stowers Institute, USA) challenged us to test the regenerative capacities of planarians. He proposed we perform experiments from different kinds of amputations to even tissue transplants, experiments that we would follow for the rest of the course. But his module projected outside the lecture room and the lab. He took us to the closest beach to CIMARQ to get samples of the living creatures that inhabit the Quintay coast. We were impressed by the rich animal diversity that lived there of a variety of shapes and colors. For some of us, it was the first time that we could see, touch and study marine organisms such as sea stars, snails, anemones and a variety of worms including planarians.
The first week ended with a lecture by Prof. Alfonso Martinez Arias (University of Cambridge, UK) on gastruloids and mouse stem cells. He engaged us in a discussion about the philosophical aspects of developmental biology. “Do you think a machine can be an embryo?” he said, to our astonished faces. These sorts of questions lit a heated debate. We discussed the manipulation of human stem cells and embryos, the possibility to compute embryonic development and the limitations of modeling biological phenomena. A key idea that emerged from the conversation, was that we should start talking about “research organisms” instead of “model organisms” because ultimately a model organism only models itself. The group was surprised and motivated by the questions, and the conversation was inspiring: at the end of the day, nobody was indifferent.
Led by Profs. Sally Moody (The George Washington University, USA), Roberto Mayor (University College of London, UK), and Fernando Faunes (University Andres Bello, Chile) the Xenopus module then came into the picture. After enlightening and fulfilling lectures, the practical activities were free and diverse. We were able to choose from a variety of different experiments to learn about axis development and the dorsal organizer inductive properties in Xenopus. Starting with different practical techniques to manipulate embryos – even using an eyebrow as a tool – we were challenged to graft neural crest cells from a fluorescent donor embryo into a wild-type host embryo. Despite the high handling complexity of this experiment, many of us succeeded and were able to record the neural crest migrating in living embryos. This module ended up with the presentation of our results and a funny awards ceremony.
To conclude the organism modules, Profs. Andrea Streit (King’s College London, UK), Claudio Stern (University College London, UK), and João Botelho (Pontificia Universidad Católica de Chile) guided us through the fascinating world of chick development. In very didactical, histrionic and immersive lectures with Claudio, we studied concepts such as regulative development and cell states during early chick embryo development. Then, Andrea brought our attention to non-coding regulatory regions in DNA and regulation of gene expression in the context of sense organ development. In the laboratory, we did ex ovo culture of primitive streak stage embryos and we injected DiI or DiO in Hensen´s node and could follow cell fates and see a fluorescent notochord the next day. We also did in ovo culture experiments and tried methods such as electroporation, to introduce morpholinos, and adding beads to the embryos to study limb development. Inspired by the organizer transplant experiments in Xenopus we asked to do something similar with chicken embryos. Andrea, who is an expert in node transplantation, quickly taught us this technique and the next day we were able to discuss the inductive capacity of the node according to the region where it had been transplanted.
A week into the course we had the opportunity to attend the “Developmental Biology Symposium-Quintay 2020”. Researchers from different universities of Chile came to Quintay to share their work, integrated with talks of some professors of the course. It was an amazing event to get to know the high quality and engaging science developed in Chile.
During the course, the most important complementary activities were the student talks in the evenings. Here, we had the opportunity to introduce our own research projects to the whole group in a very comfortable and relaxed setting, enjoying drinks and snacks during the presentations. The variety of research organisms was amazing, from Drosophila, Zebrafish, Medaka, C. elegans, passing through Xenopus, Axolotls, and even Cestodes and wild Planarian species. Even the experimental approaches varied from one to another, from molecular biology to very robust bioinformatics. The discussion that came up was very helpful, adding different classical and new approaches that we could use in our projects. On many occasions, it was so interesting that we kept talking about it in our lab nights, where the fun lasted until late and we would finish our experiments and record our results with a confocal microscope, with essential help from Jaime Espina (University Andres Bello).
Although all these activities sound tough and demanding, occasions to give our minds a break and enjoy a relaxed conversation were not missing. Besides the lunch time and student talks, we were able to organize a BBQ with our professors and fellows. Here, we got to know each other better, discuss in a relaxed atmosphere, and why not?, laugh with some jokes and chat about life (our life, not the embryo’s!). Another memorable activity was a visit to a neighboring beach, where together with some faculty we were able to enjoy a nice picnic next to ocean. All of this highlights how engaging this course is, how interaction between students and professors, even outside a purely academic context, lies at its heart.
To close these awesome weeks, the closing ceremony was presided over by Prof. Ángela Nieto (CSIC-UMH, Spain), with a lecture of the most recent findings of her laboratory, including the blended study of gene expression profiles, the physical, and cellular variations controlling normal development, metastasis, and cell proliferation. Afterwards, the professors awarded Ailen Cervino and Nicolas Cumplido with a well-deserved reward, which will enable them to attend the next “Embryology: Concepts & Techniques in Modern Developmental Biology” MBL course. Finally, we had lunch together on the Quintay coast, enjoying such good company and filled with energy, looking ahead for our own goals.
A year has passed since “Quintay 2020” took place, a few months before the Covid-19 pandemic broke out. We didn’t know then how fortunate we were to carry out face-to-face discussions, share the bench with other students and professors, or even enjoy a BBQ with people from all over the world! Even though much effort has been placed in order to continue with courses and meetings online, being able to experience a practical course like this one in real life, we believe, has transcendental effects on its students, both at the personal and professional level. Hopefully, new generations of Developmental Biologists will draw on the “Quintay experience” in the near future.

In the latest episode of Genetics Unzipped we’re taking a look at the life of JBS Haldane, whose work, writing and dominant personality made him one of the most interesting characters of 20th century genetics.
As well as being an insightful scientist, fearless self-experimenter and artful communicator, Haldane’s political leanings also affected his approach to science – even at the expense of the scientific rigour that he usually applied to his endeavours.

‘Cell-to-cell heterogeneity in Sox2 and Brachyury expression ratios guides progenitor destiny by controlling their motility.’
A Research Associate post is available in the Morphological Evolution Research Group led by Emília Santos in the Department of Zoology at the University of Cambridge. The preferred start date is 1st May 2020. The successful candidate will join a vibrant and inter-disciplinary research environment with an excellent international reputation. They will work as a key member of our research team investigating the genetic and developmental mechanisms underlying organismal diversification.
More specifically, the Postdoctoral Researcher will investigate neural crest cell evolution in cichlid fishes. Neural crest cells are a multipotent embryonic cell population that emerge from the vertebrate dorsal neural tube during early development. They then delaminate and undergo some of the longest migrations of any embryonic cell type to give origin to multiple derivatives such as pigment cells, neurons and glia of the peripheral nervous system, smooth muscle, craniofacial cartilage and bone. Many of the features that distinguish vertebrates from their chordate relatives are derived from the neural crest, making this multipotent embryonic cell population a key innovation central to vertebrate evolution.
The successful candidate will compare neural crest development across different cichlid fish species harbouring variation in neural crest derived traits (e.g. pigmentation patterns and craniofacial skeleton), to determine when and how variation in neural crest developmental mechanisms shapes adult trait morphology in a set of extremely closely related species. The project will involve the use of diverse setof techniques such as in situ hybridisation gene expression assays, live imaging of fluorescent reporter lines, and single cell RNA sequencing.
We are looking for a highly motivated candidate with a strong interest in evolutionary developmental biology, comparative embryology, and genomics. The Department of Zoology has a strong Evolutionary and Developmental Biology group, with researchers working in a variety of different organisms. The Department provides access to state-of-the-art imaging and sequencing facilities. Furthermore, the Research Associate will work in close collaboration with other groups in Cambridge working on cichlid population genomics (Prof. Richard Durbin) and epigenetics (Prof. Eric Miska).
Applications should include a motivation letter, a CV and contact details for at least two referees (more information here https://www.jobs.cam.ac.uk/job/28629/). We are committed to increasing diversity, equity and inclusiveness in STEM and encourage applications from underrepresented groups.
