Alejandro received his Ph.D. in Chemical Engineering in 2026 from the University of California, Davis under the supervision of Professor Jennifer S. Curtis. His doctoral work focused on developing advanced Discrete Element Method (DEM) simulations in an in‑house code incorporating rigid‑body mechanics, elastoplastic bonded sphere models, and particle scale deformation. He investigated how surface roughness influences granular flow behavior using a custom DEM shear cell framework. Alejandro also partnered with Lawrence Livermore National Laboratory to study cold spray deposition through coupled CFD–DEM nozzle‑flow modeling and an elastoplastic bonded‑sphere approach for the fabrication of solid‑state batteries.

Alejandro completed an internship at PSRI, where he designed a novel single‑impact attrition unit to evaluate the effects of fines and process conditions on particle breakage. He conducted similar attrition studies using a full ring shear cell. Alejandro has been active in the broader particle‑technology community through technical presentations, co‑chairing AIChE meeting sessions, collaborative research efforts, and contributions to industrial problem‑solving in granular mechanics.

Beyond research, Alejandro has been involved in organizations supporting higher education, including the Society of Hispanic Professional Engineers (SHIP). He also served as a physics, and Spanish tutor during his undergraduate studies and has frequently been a graduate teaching assistant in subjects such as fluid mechanics and thermodynamics.
