About Nathan

Nathan Seifert joined the faculty of the University of New Haven in August 2021. His research interests since graduate school have focused on the development of chirped pulse Fourier transform microwave (CP-FTMW) spectroscopic techniques, and applications of CP-FTMW spectroscopy for both physical chemistry and analytical applications. Though much of his previous research has been on the experimental aspects of molecular spectroscopy, Nathan has a strong interest in applying data science and machine learning techniques for the automated interpretation of molecular spectra in analytical chemistry and structure determination.

Nathan’s research at the University of New Haven going forward will center on development of a low-cost CP-FTMW spectrometer for structure determination and chemical mixture analysis, and the development of software and machine learning techniques for digital signal processing, spectral assignment, structure elucidation, and novel improvements to the software-hardware instrument interface.
