Prof. Rudresha Kottani

Education:



  • Ph.D. in Pharmaceutical Chemistry “ Chemical and Biological Studies of Natural and Synthetic Products”. Gulbarga University, India (2000).

Professional Experience:



Research Scientist:

Department of Chemistry,

(06/06---Current) University of Arizona, Tucson, AZ, USA

Sponsor: NSF, USA
In fast-paced environment, working on the project which involves the development of catalyst for the production of Hydrogen (Green Chemistry). Synthesized a series of nitrogen heterocycles (bipyridine systems) for the studies in developing a catalyst for Hydrogen production. Developed and introduced new techniques of synthesis to improve the yields of the target molecules.
Post Doctoral Research Associate:

Department of Chemistry,

(01/2004---06/2006) University of Denver, Denver, USA

Sponsor: NSF, USA
In a dedicated and result oriented lab, involved in the synthesis of photolabile adducts (xanthones, thioxanthones, benzophenones, dithianes). These molecules were successfully employed and played a critical role to develop a promising methods in combinatorial library screening, drug delivery and fluorescence applications. I made major contributions in developing a method for screening of solution phase combinatorial libraries. This method is considered as novel and helps to overcome the difficulties in screening combinatorial libraries.
Post Doctoral Fellow:

Department of Chemistry,

(01/2002---12/2003) National Chung Cheng University, Taiwan (R.O.C)

Sponsor: Auspex Pharmaceuticals, USA
In an industry sponsored project, engaged in developing a efficient, cost-effective synthetic strategy to prepare building blocks which are of industrial use. Designed and synthesized large number of molecules (deoxysugars, deoxyazasugars) in an efficient way to obtain stereodivergent, enatiomerically pure organic intermediates. These compounds are now being employed in pharmaceutical industry for the synthesis of target molecules for anti-viral deceases.
Professional Honors:

British Council Fellowship (1997)

Research Fellow of AICTE, India

University Merit Studentship
Research Summary:

Involved in the Design and Synthesis of Organic molecules which are employed in Pharmaceutical, Agrochemical, Cosmeceutical, Combinatorial, Green Chemistry and Industrial applications.
