 Dr. Sheeba Malik | computational biology | Young Scientist Award

Dr at University of Tennessee United States

I am a post-doctoral research associate at the University of Tennessee, Knoxville, jointly working at Oak Ridge National Laboratory. My expertise lies in modeling membranes in solution using GROMACS software. My research encompasses understanding dynamic and structural changes in membranes under various conditions, such as phase transitions, hydration changes, temperature variations, chain lengths, different salt concentrations, and solvents. I have experience in coding with MATLAB, Fortran, Mathematica, and shell scripting. I earned my Ph.D. from the Indian Institute of Technology, Jodhpur, where I developed in-house code for analysis. I have published 8 peer-reviewed articles, with 5 as the first author, focusing on phase transitions of bi-layers with biological and industrial significance.
