David F. Underwood, Ph.D.
President
underwood@underwoodpatents.com
Dr. Underwood has extensive experience in the fields of ultrafast laser spectroscopy, alternative energy, nanotechnology, and advanced materials. Dr. Underwood began his career in science with a bachelor's degree in chemistry from Colorado State University. From there, he obtained a Ph.D. in physical chemistry, with a focus on ultrafast spectroscopy, photovoltaics, and nanotechnology from Vanderbilt University. As a postdoctoral research associate at the University of Minnesota, Dr. Underwood built ultrafast laser systems and performed cutting-edge research in ultrafast spectroscopy, in collaboration with Professor David Blank.
As an author or co-author of over 20 scientific publications, Dr. Underwood enjoyed a distinguished career in experimental science before transitioning to the field of patent law. Dr. Underwood is a registered United States patent agent who developed his legal skills during his tenure at the law firm of Fish & Richardson, P.C. During that time, he was engaged in both litigation and prosecution matters in a wide variety of technology areas. He is a member of the National Association of Patent Practitioners.
Dr. Underwood lives near Minneapolis, MN with his wife and two daughters. He has a strong commitment to community service, serving as an EMT and captain on his city's volunteer fire department, and is also a licensed pilot and skydiver.

Andrew T. Healy, Ph.D.
Senior Associate
healy@underwoodpatents.com
Dr. Healy has extensive background in experimental and theoretical chemical physics. Dr. Healy began his scientific career with a bachelor's degree in biochemistry from Iowa State University. From there he earned a Ph.D. in chemical physics from the University of Minnesota where he studied electron propagation in condensed phase media using intense ultrafast laser fields.
His experimental and theoretical research earned him academic honors, including the Overend Award for Graduate Research in Physical Chemistry, which is awarded to only one graduate student per year. Dr. Healy has been a postdoctoral Fellow at the University of California, Berkeley, and the University of Minnesota, collaborating on building an ultrafast pulsed X-ray spectrometer and measuring ultrafast dynamics of photovoltaic materials, respectively.
Dr. Healy has published cutting-edge research in physical chemistry and presented his findings at distinguished conferences. Dr. Healy has served as a YMCA Senior Director, enjoys running marathons, building or restoring just about anything, playing music, constructing timber-frame and log buildings, and spending time with his two sons.
