Research Interests

Biomarker discovery, recombinant protein production and diagnostic development

Research Summary

I am highly interested in identification and validation of novel biomarkers for efficient, affordable and early-diagnosis of human diseases. I am equally interested to understand bioprocess to improve industrial production of recombinant proteins for diagnostics and/or therapeutic use.

OMICS has been the tool of my interest for the purpose.

 

Research Experience

a. Postdoctoral Researcher at Institute of Applied Microbiology, BOKU, Vienna, Austria

Area of Research

- Cell line and Process development (collaborative project with Pfizer and Lonza Biologics)

- Biomarker discovery for regulated cell growth

 

b. Postdoctoral Researcher at Dublin City University, Dublin, Ireland

Area of Research

- Cell line and Process development (collaborative project with Pfizer)

- Biomarker discovery for breast cancer

 

Scientific Contributions

I have identified a list of proteins and miRNAs that are involved in regulation of cell growth and hypoxic conditions. This may be important to understand the biology of various cell proliferation associated disorders, such as cancer and aging, as well as development of host cell line for efficient recombinant protein production.
