Xin Jin
Assistant Professor
Department of Neuroscience
The Scripps Research Institute
What is your current research?
My longstanding interest is to understand how brain development is shaped by genes and environment, and how these factors affect specific cell types to alter brain networks and function. My recent work focused on building technologies for scalable genetic screening to study the functions of risk genes in psychiatric disorders. This approach, termed in vivo Perturb-seq, helped identify diverse disease-associated mutations affecting convergent cell types and molecular pathways in autism and developmental delay.
In my own lab (starting Fall 2021), I will continue to invent genomic technologies for biological discoveries in brain development. Specifically, I will focus on studying the confluence of genes and sex-differential hormones during “critical periods” in early life. The combination of genes and hormonal physiology can mediate irreversible changes in brain development, which is not only an important basic scientific goal but also has broad translational potential for sex-biased psychiatric disorders such as autism. I am very excited about these new directions and want to shout out that if they sound interesting to you, please reach out as we will be hiring soon for all levels of scientists to join us!
What is your past research experience (if any)?
I was trained as a chemist, building chemical biology tools to allow live-cell fluorescent imaging and in vivo metabolic profiling. Aspiring to solve biological problems, I studied neuroscience in my PhD and established a behavioral paradigm to ask how early-life learning gives rise to life-long memory. I am grateful that these training experiences in both tool development and mechanistic neuroscience give me new angles and perspectives and inspire me to design and develop quantitative tools and approaches to study the brain.
How did you become interested in science?
I spent much of my childhood playing in a botany garden at the research institute where my grandpa worked. Encouraged by my grandpa, who is a taxonomist, I drew pictures of tropical plants and learned how to distinguish two species with slight differences. I could never forget the moment when I told grandpa with pride that I wanted to be just like Carl Linnaeus—to understand lives through taxonomy. Twenty years later I have clearly failed my dream to become a plant biologist. But many of these concepts remain central in my current research, to catalog and classify brain cells based on their transcriptomic similarities and hopefully to use these approaches to understand brain function as well as dysfunction.
What do you think is one major change that is needed to improve diversity, equity, and inclusion in the scientific enterprise? How do you plan to use your career to help make this change?
Presence is not inclusion; I think it is crucial to promote not only the presence of diversity in the communities but also make sure the underprivileged minorities have the same quality of experience to learn and to grow. As a soon-to-be lab head, I will be committed to mentoring qualified students and scholars from underprivileged and underrepresented backgrounds. I will reach out to them and offer to discuss their experiences for both academic and personal growth. By managing a friendly classroom and work environment, I will welcome students from diverse backgrounds, encourage them to speak in the discussions, and make proper changes to adapt the curriculum to serve the needs of all students to ensure everyone’s scientific and career success.
