Dr. Eric Lima received his doctorate in Biomedical Engineering in 2008 from Columbia University. His research focused on the regeneration of cartilage and bone using living cells. He built custom-designed bioreactors for orthopedic applications. At Cooper Union he continues his tissue engineering research while bringing hands-on teaching and design expertise to the classroom. Dr. Lima teaches basic design classes that utilize milling machines, welders, lathes, and other large equipment. Students then combine these mechanical instruments with electrical components and computer programs to prototype their ideas. He is active in the open-source hardware community and is building a library of open-source designs for equipment used in a laboratory.
