Prior to his tenure at TAMIU, he taught at The University of Texas at El Paso, Johns Hopkins University, and Towson State University in Maryland. Dr. Hinojosa held a B.Sc. in Physics and Mathematics from Brown University and both an M.A. and Ph.D. in Geophysics from Johns Hopkins University. He grew up in Nuevo Laredo and Eagle Pass, and his academic journey and professional contributions were marked by a passion for advancing the field of geophysics. The funeral arrangements were held at Hillside Funerals & Cremations; 310 W. Hillside Rd.; Laredo, TX 78041.

On Friday, May 2, 2025, the COAS Office of the Dean Brown bag Series hosted a memorial in room AIC 127 to honor the life and legacy of the late Dr. Juan Homero Hinojosa, Professor of Physics in the Department of Mathematics and Physics at Texas A&M International University (TAMIU), Laredo, Texas.

Dr. Hinojosa served TAMIU for over three decades in various key leadership roles, including as Dean of the former College of Science and Technology and as Chair of the Department of Natural Sciences. His sudden passing deeply impacted the TAMIU community and beyond. The event, co-organized by the COAS Space Exploration and Aviation program and the Department of Mathematics and Physics, served as a heartfelt tribute to Dr. Hinojosa’s many contributions, his distinguished career, and, above all, his valued friendship and collegial spirit. The memorial included remarks and tributes from faculty, students, and friends:

Dr. Robert W. Haynes, Regents Professor and Regents Fellow (2021–2022), shared personal reflections on his friendship with Dr. Hinojosa and recited a poem in his memory. The event concluded with closing remarks from Dr. Marcus A. Ynalvez, who expressed gratitude to all in attendance for joining in this final Spring 2025 COAS OD Brown bag to honor Dr. Hinojosa’s enduring legacy.

May his legacy last forever!

Dr. Qingwen Ni Retired!

Dr Qingwen Ni

A TAMIU longtime Professor Physics, Dr. Qingwen Ni, retired at the end of January 2025. Dr. Qingwen Ni carried out some important research projects funded by NIH, NSF, and TAMIU on Nuclear Magnetic Resonance research, applications, and development. He was also awarded the SOY of the University in 2009 and 2015, respectively. Dr. Ni thoroughly deserves this recognition for his work as a faculty in the Department of Mathematics and Physics.

Graduate Open House Photo

Development of the MS in Mathematics-Applied Statistics track has taken place this summer. Several students have already enrolled in the courses for this upcoming Fall semester. With the rapidly increasing needs for dealing with big data, students can choose a combination of courses from both mathematics and applied statistics that can be strategically aligned to their background and career goals. Our small class sizes provide close personal attention from our active research-oriented faculty members. Graduates can pursue job opportunities such as actuaries, statisticians, or teachers in secondary schools or two-year colleges. Graduates can also transition to doctoral programs elsewhere.

Online Astronomy Courses

Dr Juan HinojosaPeter Davis

Effective Fall 2016, both the Astronomy course and its corresponding laboratory will be offered online. The pilot project conducted for the Astronomy lab offered this summer has been a success. Both Dr. Juan H. Hinojosa and Mr. Peter S. Davis are commended for undertaking the online delivery of the course and the lab, respectively. This is the first time a science course sequence is offered online at TAMIU to accommodate time constraints faced by students taking on the dual role of parent and employee.
