Abraham A. Paul is a short-term postdoctoral researcher in Biotechnology Engineering at Ben-Gurion University of the Negev, Israel. His research focuses on developing alginate-based composite hydrogels for biosensing and regenerative medicine. Through photochemistry, EDC/NHS coupling, and nanoparticle integration, he engineers hydrogels with enhanced reactivity, electrical conductivity, and magnetic responsiveness. His recent work includes covalently conductive alginate-polypyrrole composites, photoactivatable alginate–benzophenone systems, and alginate-coated magnetic nanoparticles for antimicrobial biosensing and enzyme immobilization. Abraham has extensive experience in extrusion-based 3D bioprinting, flow-cell biofilm inhibition, Fmoc solid-phase peptide synthesis, and core–shell microencapsulation for biosensor applications. He holds First-Class Honours and Distinction degrees in Biochemistry from Kaduna State University and Obafemi Awolowo University, Nigeria. With over 15 peer-reviewed publications and additional manuscripts in progress, he has also explored marine and plant-derived bioactive compounds with antihypertensive, antimalarial, and immunomodulatory potential. His research vision centers on multifunctional nanogels for in vivo imaging and theranostics.
