Liu Lab Equipment & Research Environment

Our laboratory is on the top floor of the BSE building in the main campus of UTSA, which is an $84 million 227,000 square feet, a five-story structure built 14 years ago. Our laboratory room numbers are BSE 0.110 (EPR), 4.204 (rRaman), 4.314 & 4.320, and our offices at 4.206 (postdocs') and 4.314 A&B (students'). Our lab has received the Excellence in Laboratory Safety in the UTSA Gold Star Lab Safety Program and Outstanding Commitment to Laboratory Safety Culture award.
