Summary

I develop and use theoretical and computational techniques to characterize and study bio-molecular systems to aid computer-aided drug design with a focus on docking-based and pharmacophore-based virtual screening, homology modeling of proteins, hit identification and hit to lead and multi-parameter optimization. Experience with statistical mechanics, conventional and enhanced-sampling molecular dynamics (MD) simulations, constant pH simulation, coarse-grained simulation, and quantum mechanical (QM) calculations. Skilled in free energy calculations specially using the free energy perturbation (FEP) method to study receptor-ligand binding and the importance of water to binding. Strong background in python and machine learning. Enjoy interacting with scientists from different disciplines and the challenges of designing models to complement experimental needs. Able to work in high-stress situations and can handle multiple projects at the same time. A highly motivated researcher who is keen to pick up new skills rapidly. Hardworking Postdoctoral Research Fellow with demonstrated record of research success in. Self-directed and motivated professional with highly-ethical, meticulous and thorough approach.

  • Developed new Artificial Intelligence (AI) methods for studying behavior of protein related to neurodegenerative diseases such as Alzheimer's disease in changing ocean conditions.
  • Performed scientific research on multiple projects in collaboration with multidisciplinary teams
  • Designed and carried out complex computational experiments to assess effectiveness of novel drug compounds.
  • Authored professional scientific papers for publishing in peer-reviewed journals.
  • Edited papers for submission to prestigious academic and industry journals.
  • Mentored junior researchers, providing guidance on study design, data analysis, and manuscript preparation.
  • Secured grant funding for further research projects by submitting well-crafted proposals and demonstrating solid preliminary results.

Postdoctoral Research Associate

Michigan State University
02.2022 - 01.2023
  • Using MD simulation with enhanced sampling (weighted ensemble simulation) and Machine Learning algorithm to analyze potency in term of the binding mechanism of tail spike protein of bacteria-infecting viruses, known as bacteriophages, to infect shigella flexnery bacteria causes bacillary dysentery and shigellosis in human
  • Also analyzed the significant non-covalent interaction playing a crucial role in binding between them
  • Investigated how the mutation of tail spike protein of bacteriophage impacts the catalytic activity to cleave the bacteria O-antigen carbohydrate by hydrolysis, which allows it to reach the surface and infect the bacterium
  • Identified the mode of interaction of the antagonist KCI807 with androgen receptor using systematic mutagenesis to block the binding of ELK1 to inhibit prostate cancer growth in collaboration with the researcher from the oncology department of Karmanos Cancer Institute.(Manuscript is recently accepted in journal of Molecular Pharmacology)

Graduate Research Assistant

University of New Orleans
08.2018 - 12.2021
  • Using the homology model (Alphafold and Swiss-model) to predict the three-dimensional structure of SARS-CoV-2 helicase from its primary amino acid sequences (when we started this work, the tertiary crystal structure of SARS-CoV-2 helicase was unknown)
  • Used an enhanced molecular dynamics simulation method (replica exchange) to understand the SARS-CoV-2 helicase protein's structural flexibility and developed a new approach to help in the identification of allosteric sites
  • Also proposed potential inhibitors for this newly revealed allosteric site by virtual screening such as molecular docking (Glide and Autodock Vina) of 10 million compounds
  • Developed an accurate molecular model of water and, using this model, analyzed the hydrophobic effect by studying the thermodynamics properties
  • Applied ligand-based pharmacophore modeling combined with structure-based docking and molecular dynamic simulation to introduce novel inhibitors needs of patients with Alzheimer's disease
  • Used more than 500,000 molecules from publicly available databases such as Cambridge, Kinacore, and Zinc for virtual screening like molecular docking (GOLD 5.1 and GLIDE 5.5 programs)
  • Also, activity, toxicity, and physicochemical and pharmacokinetic properties are analyzed
  • Used the DEREK program for the analysis of toxicity such as mutagenicity, carcinogenicity, skin sensitization, irritation, reproductive effects, and neurotoxicity
  • Physicochemical and pharmacokinetics properties such as absorption, distribution, metabolism, and excretion is analyzed using the QikProp (Developed by Schrodinger) program
  • Developed a coarse-grained models for molecular dynamics simulations of pH-sensitive drug-delivered polymers
  • Collaborated with researchers at other universities to develop Coarse-grained models for polypeptoid.

Application Scientist

  • Performed Free energy Perturbation (FEP) simulation to characterize the binding of small molecules to the E3 ligase proteins (VHL and Cereblon) as a part of designing heterobifunctional small molecule proteolysis targeting chimeras (PROTACs)
  • Partnered with one of Schrodinger's customers to predict the binding energy of a total of 128 VHL binders.

Computational Chemist

Boehringer Ingelheim
