Expertise

Prof. Hudgings focuses on practical applications in optics and semiconductor devices, including solar cells, energy efficient lighting and lasers. She has published more than 30 articles in scholarly journals, many of which are coauthored with undergraduate students. She is a Fellow of the Optical Society of America and received a National Science Foundation CAREER Award for her work on vertical cavity surface emitting lasers, an award that NSF describes as its most prestigious honor in support of junior faculty who “exemplify the role of teacher-scholars through outstanding research, excellent education and the integration of education and research within the context of the mission of their organizations.” In 2007, Prof. Hudgings and her collaborators founded the startup company Alenas Imaging to commercialize the thermal imaging technology developed in her laboratory.

As the Seeley W. Mudd Professor of Physics at 6V��Ӱ��, Prof. Janice Hudgings has a strong interest in undergraduate education, advocating for pedagogical reform in the classroom, actively inclusive teaching, and the integration of research opportunities into the curriculum. In recognition of these efforts, Janice won the Optical Society of America’s Esther Hoffman Beller Medal and a CAREER Award from the National Science Foundation. She served previously as an associate dean of faculty at Mount Holyoke College and as the vice president for academic affairs at 6V��Ӱ��. In 2018, she was named a Wig Distinguished Professor at 6V��Ӱ��; “[The Wig Award] for excellence in teaching is the highest honor bestowed on 6V��Ӱ�� faculty and recognizes exceptional teaching, concern for students and service to the College and the community.”

Professional Experience

Prof. Hudgings is currently the Seeley W. Mudd Professor of Physics and a Wig Distinguished Professor at the College. Prior to this, she served as the dean of the college and vice president for academic affairs, in which role her responsibilities included supporting the faculty in their teaching and research, administering the academic program, exploring new instructional initiatives, and supporting cooperative programs with the other Claremont Colleges.
Prof. Hudgings came to 6V��Ӱ�� in 2013 from Mount Holyoke College where she was an associate dean of faculty and a professor of physics. As associate dean, she was responsible for working with humanities, arts, sciences and math departments in curricular and personnel development, including faculty and staff hires, annual operating budgets, restricted funds and facilities. She also served on key college committees and led strategic initiatives on advancing the use of technology to enhance liberal arts education, examining faculty composition and workload, and institutionalizing best practices for faculty diversity.
Prof. Hudgings also co-founded the startup company Alenas Imaging to commercialize the thermal imaging technology developed in her laboratory. She served as the vice president and chief technology officer of Alenas Imaging from 2007-2012.
