Joseph D. Fehribach

Joseph D. Fehribach is a Professor of Mathematical Sciences at Worcester Polytechnic Institute (WPI), where he has taught and led mathematical research efforts since 1992. His office is located in Stratton Hall 316, and he can be reached at +1 (508) 8315000 x5069.

His educational background includes:

• BA in Mathematics and Physics from Centre College, Summa Cum Laude (1980)
• MA in Mathematics from Duke University (1982)
• PhD in Mathematics from Duke University (1985)

Professor Fehribach's research spans the theoretical and applied mathematics domains, with primary focus on Kirchhoff graphs and porous electrodes in electrochemical systems. His Kirchhoff graph work explores how null and row spaces of matrices form orthogonal complements, providing circuit diagram representations for chemical reaction networks. In electrochemistry, he investigates diffusion-reaction-conduction processes in porous electrodes, particularly for fuel cell applications. His approach combines rigorous mathematical theory with practical scientific computing techniques to solve complex problems in energy technology.

Analysis of his publication history reveals an evolving research trajectory from specific fuel cell modeling in the 1990s-2000s toward more general mathematical frameworks like Kirchhoff graphs in later years. His work consistently bridges abstract mathematical concepts with tangible electrochemical applications, demonstrating how graph theory can illuminate complex chemical reaction networks and how differential equations model physical phenomena in energy systems.

His scientific recognition includes:

• Faculty Honors Convocation (2017)

Professor Fehribach has maintained an active research program for over three decades at WPI. He has engaged with contemporary issues, authoring a 2020 opinion piece for the Telegram & Gazette on widespread COVID-19 testing strategies. While specific details about his advised students aren't provided, his sustained research output suggests significant mentorship activities. His work on mathematical modeling of electrochemical systems likely involves interdisciplinary collaborations across mathematics, chemical engineering, and materials science departments.

Though not explicitly detailed in available materials, Professor Fehribach's research program likely operates within WPI's mathematical sciences infrastructure, potentially connecting with energy research centers focused on fuel cell technology and electrochemical systems where his expertise in porous electrode modeling provides critical mathematical foundations.
