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.

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 received my PhD in Nutritional Sciences from Rutgers University, where I studied nutrient-sensing pathways and their roles in regulating physiological processes such as heat production and circadian rhythms. As a postdoctoral fellow in the Panda Lab, I am conducting clinical research to gain mechanistic insights into how time-restricted eating can be leveraged to support health, longevity, and performance in humans. Outside the lab, I stay active through outdoor activities and strength training, which keep me balanced and inspired.

I received my PhD in Molecular Physiology from UC Davis in June of 2023. Here, my research focused on understanding how diet effects skeletal muscle metabolism and cognitive function. I joined Dr. Panda’s lab as a postdoctoral researcher in September 2023 and am part of the Wu-Tsai Human Performance Alliance. Currently, my research focuses on delineating the role of timing and content of nutrition on skeletal health, metabolism, and performance. Outside the lab, I enjoy exercising, spending time loved ones, and binge watching tv shows while slowly becoming one with the couch.

Adam Rochussen

I joined the Panda lab at the start of 2025 as a postdoc. I did my PhD at University of Cambridge in the lab of Gillian Griffiths, where I studied the cell biology of cytotoxic T lymphocytes. Broadly, I care about how behavioural interventions can impact the immune system. Here, I’m interested in how the molecular clocks of T cells are regulated, and how circadian synchronicity in immune cells affects their function, particularly in the context of cancer and immunotherapy. Outside of the lab, I am somewhat of a coffee connoisseur, I do a lot of physical fitness and sports, and I enjoy reading and writing things.
LAURA

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.

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!

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.

Aidan-Galina

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.
