Research Interests: cell and tissue engineering, biomaterials, and biomechanics

Gigi received her B.S. in Biomedical Engineering from University of California, Davis in 2022. While there, she conducted research In Dr. Kent Leach's Lab that focused on the development of tissue engineering solutions for osteochondral defects, specifically using polymer-based biomaterials. After being exposed to the crossover of orthopedics and biomedical engineering, she decided to attend Columbia and join Nadeen Chahine's lab. In her free time, she enjoys skiing, going for walks in Central Park, finding new fun places to eat, and exploring New York with friends. 

 

Maho Koga, M.Eng; Graduate Student (PhD program) in Biomedical Engineering

Email: mk4795@columbia.edu

Research Interests: tissue engineering, biomechanics, and biomaterials

Maho Koga is a PhD student in Biomedical Engineering co-advised by Dr. Nadeen Chahine (Chahine Lab) and Dr. Helen Lu (Biomaterials and Interface Tissue Engineering Laboratory). Maho is interested in pursuing research in the field of orthopedics, specially looking at tissue-engineered therapies for intervertebral disc degeneration in the spine. She obtained her B.S. in Biological Engineering and M.Eng in Biomedical Engineering from Cornell University, where she previously conducted research under the supervision of Dr. Eve Donnelly for undergraduate research and Dr. Lawrence Bonassar for her Master’s. She worked in the pharmaceutical industry for 2 years after graduation and is excited to begin her PhD at Columbia University.

Email: nt2639@columbia.edu

Research Interests: cell image analysis, injury biomechanics, and sports medicine

Nick earned a B.S. in Biomedical Engineering from Pennsylvania State University. During his undergraduate studies, Nick delved into the intersection of biomechanics and accident physics, using engineering principles to analyze the forces and accelerations in vehicular accidents. This research played a critical role in personal injury litigations, providing expert witness testimonies based on injury causation and related mechanisms. Now pursuing a Master's degree in Biomedical Engineering at Columbia University, Nick has expanded his expertise to areas like cell image analysis, mechanobiology, and orthopedic regenerative medicine. Currently, Nick is working on an AI-based automated cell image analysis, having developed a promising diagnostic pipeline that differentiates between healthy and diseased cell types. Driven by a passion for merging technology with healthcare, Nick is keen on exploring real-world challenges in the biomedical realm.
