Staff Scientist
Natural Products Chemistry Section

Dr. Grkovic is a natural product chemist with an interest in understanding the structure and function of natural products in the early stages of drug discovery. She has extensive experience in the generation of natural product libraries for high-throughput screening and the isolation and structure elucidation of small molecules from marine, plant, and microbial biota.

Areas of Expertise

1) natural products, 2) prefractionated libraries, 3) NMR spectroscopy, 4) structure elucidation of small molecules, 5) high-throughput screening

Our work is focused on the isolation and identification of biologically active marine and plant-sourced natural products with emphasis on the development and applications of novel technologies. Our research efforts include the use of prefractionated libraries in new cell-based and cell-free molecularly targeted high-throughput screens, structure elucidation of complex natural products involving a range of spectroscopic and spectrometric methods, and development of metabolomic and bioinformatic tools for the dereplication of natural products in complex mixtures.
