Principal Investigator

Satchin Panda

Satchin Panda, a professor in the Regulatory Biology Laboratory, is interested in understanding the molecular mechanism of the biological clock in a mouse model system. The biological clock or circadian oscillator in most organisms coordinates behavior and physiology with the natural light-dark cycle. His laboratory uses genetic, genomics and biochemical approaches to identify genes under circadian regulation in different organs and to understand the mechanism of such regulation. His lab also tries to characterize the mechanism by which the circadian oscillator is synchronized to the natural light-dark condition. Both classical rod/cone photoreceptors and a newly identified ocular photopigment melanopsin participate in photoentrainment of the clock. Research in his lab is geared towards identifying molecular components and events critical for transmitting light information from the eye to the master oscillator in the brain.
Postdoctoral Fellow

Hugo Calligaro

I received my PhD in Neurosciences from the University of Lyon in 2018. I joined Dr Panda’s team to study the opsins involved in the regulation of the circadian system by using a combination of approaches including histology, electrophysiology and sequencing.

Shaunak Deota

I received my PhD in Biochemistry in early 2019 from Tata Institute of Fundamental Research in Mumbai, India. I joined the Panda lab to study the molecular physiology of Time restricted feeding (TRF). Outside the lab, I love traveling, cooking and watching science fiction series/movies.
Michael Lam

Michael Lam

I am awe-struck by how many chronic diseases are intimately related to daily behaviors. I joined this lab because Dr. Panda et al. use state-of-the-art experimental techniques and interesting perspectives to examine how physiology adapts to simple behavioral changes (for better or for worse). I did my M.D./Ph.D. training at UC San Diego, focusing on the mechanism of transcriptional regulation on inflammatory responses. Clinically, I specialize in Internal Medicine with subspecialty training in Pulmonary and Critical Care Medicine. I take care of many patients in the ICU with sepsis. My goal is to understand how sleep disruption (almost a ubiquitous experience for ICU patients) affects immune response. I enjoy the multidisciplinary environment in the lab, allowing me to integrate perspectives from circadian biology, molecular biology, and behavioral physiology with my scientific passion.

I joined the Panda lab at the end of 2020. Here I am part of the Wu Tsai Human Performance Alliance, studying the role of the circadian clock in performance, injury prevention, and recovery. My interest in this topic started during my PhD in Biomedical Research at the Biozentrum, University of Basel, Switzerland, where I studied the interaction between the skeletal muscle, the circadian clock, and exercise.

Laura Van Rosmalen

I received my PhD in Neuroscience in September 2021 from the University of Groningen, the Netherlands. My research focused on photoperiodism and seasonality. I joined the Panda lab as a postdoctoral fellow in October 2021, to study the underlying mechanisms driving the timing of daily activity (i.e., diurnality or nocturnality) related to energy balance. When I’m not in the lab, I go hiking, camping or play cello.
Staff Researcher / Scientist

Hong Long

Like research, I believe that little fruit flies can teach us so many things about human brain.

Emily Manoogian

I received my PhD in Neuroscience and Behavior in 2015 from the UMass Amherst. My research focused on gaining an understanding of the behavioral, neurobiological, and genetic bases of the circadian mutant hamster known as duper. In early 2016, I joined the Panda lab to apply my knowledge of chronobiology to human translation studies. I am now the head of human research in the Panda lab, with a focus on Time-Restricted Feeding. Outside of lab, I love to travel, go the beach, sketch/paint, and tap dance!


Xiaoyan Zhu

Xiaoyan Zhu

I joined the Panda lab about 3 years ago. I am interested in understanding the molecular mechanisms underlying intricate interactions between circadian rhythm and other pathways in metabolism and cancer in cell and tissue-specific manner. In my spare time, I enjoy reading and watching movies.

Hiep Le

I joined Dr. Panda’s lab in 2005 as a research assistant. Since then I’ve worked with Xenopus laevis, Drosophila melanogaster and Mus musculus to help elucidate how the circadian clock works and what it affects. When I’m not in the lab, I’m usually taking photos or eating, or combining both and taking photos of the food I eat.

Ramesh Ramasamy

I joined Dr. Panda’s lab in early 2021 as a data scientist. I am mainly involved in integrating multi-omics data to understand regulatory elements controlling gene expression in mammals. Apart from research, I enjoy stargazing, outdoor biking, and eating what I cook.

Shweta Varshney

I joined Dr. Panda’s lab in 2020. I assist in learning circadian rhythm and factors influencing it using fruit fly as animal model. Outside the lab I love to spend time with my family and trying & learning new things.

Kyla Laing

I joined the Panda Lab as a volunteer during my second year of undergrad at UCSD and now working full-time since graduating in 2022. I support our ongoing clinical trials focused on time-restricted eating as a lifestyle intervention to improve health. I aspire to attend medical school in the future and hope to apply the principles I am learning during my time here as a future physician. In my free time, I enjoy cooking, reading, weightlifting, and yoga.


Mason Kralovec

I joined the Panda lab in the summer of 2022 after graduating from the University of California, Los Angeles with a B.S. in Neuroscience. I am interested in better defining how time-restricted eating can influence the onset and manifestations of age-related diseases like Alzheimer’s disease, specifically within the Drosophila melanogaster model. Outside the lab, you can find me hiking, lifting weights, or watching soccer.


Krushali Powale

I joined the Panda lab at Salk in January 2023 after a brief work experience at the pharmaceutical industry in India. In the Panda lab, I support projects related to screening of natural products and chemical entities. I am interested in finding molecules that may target the key components participating in the circadian rhythm using in-vitro cell line-based assays. In my free time I like to draw or sketch or make craft items. I enjoy cooking, I love ice cream and I always say yes to a cup of tea!

Yiyi Shen

I joined the Panda lab as a research assistant to gain more research experience in circadian biology before applying to a Ph.D. program. Before joining the lab, I received my biology BS/MS degree through a joint BSMS biology program from UCSD as well as a BA degree in psychology. Outside the lab, I enjoy visiting museums, making art, and crocheting.

Tyler Tran

I joined the Panda Lab in the summer of 2022 while I was an undergraduate at the University of California, San Diego. Now my work is mainly focused on data analysis, where I am specifically interested in discovering how time-restricted eating can be of benefit to the wider population and in finding how time plays a role in health. When I’m not working with data, you’ll find me learning photography, playing tennis, enjoying a cup of matcha, or at random concerts throughout the LA and SD areas.

Kelsey Fierro

I joined the lab at the end of 2022, a year after receiving my B.S. in Chemistry from UC Irvine.  I am intrigued by the body’s resilience and how daily practices can have significant contributions on overall health.  It also motivates me to know that the work we do in the lab can empower people to take ownership of their health on a day-to-day basis.  Outside of the lab I like to watch movies, go to coffee shops, and bike.

Ian Li

I joined the Panda lab as a BS/MS student in early 2022. I am interested in the role of sleep disruption in the immune response to infectious diseases and sepsis. I also work as a research assistant to help others with their projects. I enjoy photography, gaming, hiking, and fishing in my free time.
Graduate Student

Terry Lin

I joined the Panda lab as a volunteer in my third year of undergrad at UCSD and have continued on as a graduate student. My interests are of mice and metabolism. My latest goal is to learn more about circadian regulation in disease development. And drink more water.

Aidan Glina

I joined the Panda lab in 2022 as a bioinformatics & systems biology PhD student. I am interested in leveraging the large and diverse data generated in the Panda lab to study phenomena that emerge from complex systems that are more than just a sum of its parts — such as how exercise, aging, and time interact. Along with the boolean lab at UCSD, I am working on creating new analysis techniques that work to take into account the whole picture of biological systems through time. When I’m not on my computer, I like to spend my time in the ocean or playing games with my friends.
