Download Curriculum Vitae

Sabareesan Ambadi Thody, PhD, is a Biochemist currently serving as an Instructor in the Department of Biophysics at the UT Southwestern Medical Center in Dallas, Texas. His career is defined by a deep commitment to unraveling the complex mechanisms of biological systems, particularly through the lens of protein misfolding, liquid-liquid phase separation, and Protein-small molecule interactions.

Academic Foundations and Early Research

Dr. Thody's academic journey began in India at the Amrita School of Biotechnology, where he earned both his Bachelor’s (2008) and Master’s (2010) degrees in Biotechnology. His exceptional potential was recognized early when he qualified for the All India GATE Biotechnology exam with a near-perfect percentile of 99.99.

He pursued his doctoral studies at the prestigious National Centre for Biological Sciences (NCBS), Tata Institute of Fundamental Research (TIFR) in Bengaluru. Under the mentorship of Professors Jayant B. Udgaonkar and Mathew K. Mathew, his Ph.D. research focused on the structural transitions of the human prion protein. His work provided critical insights into how disordered regions in prion protein modulate prion misfolding into oligomers and amyloid fibrils, processes central to prion-mediated neurodegenerative diseases.

Pioneering Work in Biomolecular Condensates

In late 2017, Dr. Thody joined the laboratory of Professor Michael Rosen at UT Southwestern Medical Center, initially as a Postdoctoral Research Fellow before advancing to the ranks of Assistant Instructor and Instructor. At UT Southwestern, he has been at the forefront of research into membrane-less organelles, also known as biomolecular condensates, that form through liquid-liquid phase separation. His work specifically explores the "chemical grammar" governing how small molecules and metabolites partition into these unique cellular environments. This work has significant implications for drug discovery, potentially revealing how the physical environment of a cell influences the efficacy and localization of therapeutic compounds.

Beyond his research, Dr. Thody is a committed mentor and an active leader within the broader scientific community. He contributes to the professional development of the next generation of scientists and maintains a strong service record as a scientific reviewer for numerous high-impact journals. Furthermore, he remains an engaged member of premier professional organizations, including the Biophysical Society and the Protein Society.

Research Philosophy

Integrating advanced biophysical techniques, Dr. Thody’s work bridges the gap between fundamental physical chemistry and complex cellular biology. By combining high-resolution microscopy with quantitative proteomics and metabolomics-based mass spectrometry methods, he provides a detailed molecular view of the cellular landscape. This multi-omics approach allows him to push the boundaries of our understanding of how cellular components organize themselves to sustain life and how these critical processes fail in the context of disease.
