Hi, I’m Jeremy.

I’m a Ph.D. candidate in the department of mechanical and aerospace engineering at the University of California San Diego, where I am advised by Carlos Coimbra and funded by the San Diego Fellowship. I love all things science, but I’m especially interested in problem solving with the use of math, physics, and a hard-earned intuition about physical systems. I have a B.S. (2014) and an M.S. (2016) in mechanical engineering, both from UC San Diego.

I joined the Coimbra Research Group (CRG) during my junior year of undergraduate study in 2012, and since then I have been involved with a number of research projects such as resource to power modeling for large-scale solar power plants and the development of low cost, rapidly deployable, self-sustaining portable weather sensing stations. Sometimes, I build robots [1, 2, 3]. Over the Summer and Fall of 2016, I spent time working on cutting edge semiconductor chip manufacturing technology at Cymer/ASML.

Outside of research, I occasionally mentor undergraduate students on their journey toward postgraduate study through the STARS and UC LEADS programs. In the past I have also worked with the IDEA Scholars program and with high school outreach through the CRG.

My research…

…takes place in the space of nonlocal operators and variable order dynamics. My interests include identification, control, and stability; nonlinear/nonconvex optimization; and condensed matter systems.

Currently, my research efforts are directed toward the development of efficient numerical methods for the solution of variable order differential equations and the description of anomalous electromagnetic dispersion dynamics using generalized variable order models.

On the characterization of optical properties for thin metallic films

J. Orosco and C.F.M. Coimbra (provisionally accepted), Applied Optics

A recently proposed, physically consistent model for the optical response
of solid amorphous media is extended for use with conductive media.
An optimal procedure for the fitting of optical data is proposed.
The resulting parameterizations represent a significant improvement
over previously proposed, KKR-noncompliant models.

Optical response of thin amorphous films to infrared radiation

J. Orosco and C.F.M. Coimbra (2018), Physical Review B

A novel Kramers-Kronig consistent model is proposed for the electric
susceptibility of solid media. The model accurately reproduces the
broadened non-Lorentzian absorption peaks observed in the optical
response of amorphous dielectric solids.

On the control and stability of variable-order mechanical systems

J. Orosco and C.F.M. Coimbra (2016), Nonlinear Dynamics

Modern control methods are extended for use with a nonlinear system of
variable order differential equations. An analytical expression is derived for
the dependence of the closed-loop stability on the variable order damping.
