Ajay Gupta

Adjunct Professor


Dr. Ajay Gupta managed the set up of a state of the art pharmaceutical physico-chemical and microbiology analysis laboratory in Irving, Texas. Wrote a number of quality procedures including quality manual, site master file, validation master plan, several IOPQ protocols and SOPs, purchasing various analytical equipment, hiring personnel, designed mock runs, set-up training programs and setting up mock FDA and ISO17025 audits. Addressed OOSs, implemented several innovative solutions to address CAPAs as well as continually improving Medisca’s protocols to not only improve quality of its products, but also to ensure complete compliance with regulations as well as minimizing the risk to the end users. Set up occupational exposure band controls of several hundred active pharmaceutical ingredients, excipients and finished products and established and validated dose and toxicology based calculations of occupational exposure limits of pharmaceuticals based on their toxicology, pharmacokinetics, toxicokinetics and pharmacodynamics. Guided the company on formulation development, regulatory affairs, cleaning validations, stability testing, developing release specifications for new products, analytical chemistry, training staff, R&D projects including skin penetration studies, equivalency studies on packaging materials, vendor qualifications including conducting audits, stability study design etc.


Area of Interest

My research interests in oncology are currently focused on
(1) role of oxidative stress in cancer biology specially focusing on role of hemeoxygenase-1 in tumor progression and metastasis
(2) development of multi-modal anti-cancer drugs with multiple and synergistic mechanisms of anti-tumor actions
(3) development of novel anti-cancer drugs to overcome drug resistance in terminal cancers
(4) development of novel biomarkers especially prostate cancer for early diagnosis and prevention.
