Assoc. Prof. Dr. Georgios Karras | Protein Folding Chaperones | Best Researcher Award

The University of Texas MD Anderson Cancer Center | United States

Dr. Georgios Karras is a molecular geneticist whose research focuses on understanding cellular stress responses and genome stability mechanisms, with implications for cancer development and therapy. His work explores how cells maintain protein homeostasis and genomic integrity under physiological and pathological stress, integrating molecular genetics, biochemistry, and systems biology approaches. Through his research, Dr. Karras investigates molecular pathways that regulate proteostasis, DNA repair, and chromatin dynamics, aiming to uncover how their dysregulation contributes to tumorigenesis. His studies have advanced understanding of the molecular mechanisms that link protein quality control systems to genome maintenance, providing insights into how stress adaptation influences cancer cell survival and progression. Dr. Karras’s laboratory also develops innovative genetic and biochemical models to study these processes, combining yeast and mammalian systems to identify conserved stress response mechanisms. His research has received recognition through multiple national awards and funding programs, including support from cancer research foundations and the National Cancer Institute. By elucidating the interplay between cellular stress signaling and genome stability, Dr. Karras’s work contributes to the development of novel strategies for targeting stress-related vulnerabilities in cancer cells, offering new perspectives for precision oncology and therapeutic interventions.

Assoc. Prof. Dr. Afolake Arowolo | Functional Genomics | Best Researcher Award

South African Medical Council and University of Cape Town | South Africa

Dr. Afolake Temitope Arowolo is a C2 NRF-rated Specialist Scientist at the South African Medical Research Council and Adjunct Professor at the University of Cape Town, with more than a decade of experience in biochemistry, molecular biology, and functional genomics. She earned her PhD in Biochemistry from Rhodes University, and earlier degrees from Obafemi Awolowo University. Her research has spanned teaching and supervising students at undergraduate, honours and postgraduate levels, delivering courses in molecular biology, structural biology, biochemistry, enzyme and protein characterisation, as well as quality control and molecular techniques such as CRISPR-Cas9 screening, PCR / qPCR, cloning, and electrophoresis. She has published over 20 peer-reviewed research articles, including a filed patent on novel inhibitors of human 5-alpha reductase for androgenetic alopecia, and has secured various international and local grants and fellowships. Her work has been cited in the scientific literature many times, reflecting a solid h-index (approximately mid- to high-teens) and citations in excess of one hundred. She is active in editorial and peer review duties, mentors, especially for scholars from under-represented backgrounds, and her current research interest is identifying novel therapeutic agents for diseases such as diabetes cardiomyopathy, cardiovascular disease, cancer, and fibrosing skin and hair disorders, applying functional genomics, nanobiotechnology, molecular biology and enzymology.
