Associate Professor and Principal Investigator
Aerospace Engineering & Physics
Dr. Guzmán is an Associate Professor and experimental physicist with the departments of Aerospace Engineering and Physics & Astronomy at Texas A&M University (TAMU). His research focuses on the development of novel optomechanical inertial sensors, precision laser interferometry, and optical technologies for ground and space applications in gravitational-wave astrophysics, geosciences, navigation, and precision metrology. He is the PI of the TAMU groups within the LIGO Scientific Collaboration (LSC) and the LISA Consortium. Upon receiving his Ph.D. in Physics from the Max Planck Institute for Gravitational Physics in Hannover, Germany, he was awarded a NASA Postdoctoral Program (NPP) fellowship at NASA Goddard Space Flight Center with the Gravitational Astrophysics Laboratory. Later, he became a Senior Research Associate at the Joint Quantum Institute (NIST and University of Maryland) and Research Group Leader at the German Space Agency (DLR) in collaboration with the University of Bremen.

Research Associate Professor
Dr. Sanjuan is a Research Associate Professor and an electrical engineer with the Department of Aerospace Engineering at Texas A&M University (A&M). He has over 15 years of experience in space missions for gravity field and gravitational wave measurements, optical metrology, laser frequency stabilization systems and optical clocks for global navigation satellite systems and tests of fundamental physics in space. He received his Ph.D. in Electrical Engineering at the Universitat Politecnica de Catalunya (UPC) in Spain. Subsequently, he joined the LISA group at the Department of Physics at the University of Florida as post-doc. Later, he led the team at the German Space Agency (DLR) to develop the optical ground support equipment for the laser ranging interferometer (LRI) on GRACE Follow-On. In 2019, he returned to the University of Florida to work on the LISA telescope testing at the Department of Physics, and on gravitational reference sensors at the Mechanical and Aerospace Engineering Department
