Research Philosophy

I maintain a broad interest in solving problems in the fields of analog and mixed-signal information processing and electro-optic sensing using CMOS technology. We are developing a program in integrated power management circuits, and have publshed several papers on low-power linear dropout regulators. Current research includes switched-capacitor and inductor-based DC-to-DC converters. In addition, I am applying low-power analog and mixed-signal VLSI techniques for the solution of adaptive optics problems in real-time. In particular, we have developed three sensor systems:  an active-pixel image centroid sensor, an active-pixel image sharpness sensor, and a wavefront phase sensor that uses an interferometric approach. All of this research has been conducted in collaboration with the Electro-Optics Group at NMSU.

Teaching Philosophy

For undergraduate courses, I strive to develop strong critical thinking skills in students through lecture, collaborative learning, teamwork in lab, and challenging homework assignments and exams. In an effort to decrease the number of students failing a class with a D, F, or W (withdraw), I have adopted all aspects of cooperative learning in all required undergraduate courses: Positive interdependence,  face-to-face interaction, group and individual accountability, small group leadership and interpersonal skills, and reflecting on the group.  The effect has been tremendous, as I've witnessed D,F,W rates drop from 35% to 20%. Students "enjoy" the course more, and exam scores increase.   For graduate-level and undergraduate elective courses, in addition to developing strong critical thinking skills, it is my goal to bring state-of-the-art topics and CAD tools to the classroom and lab, so that graduating students are prepared to face tomorrow’s challenges in electrical engineering.

 

Administrative Philosophy

I am helping lead the NMSU College of Engineering, in general, and the Klipsch School of Electrical and Computer Engineering, in particular, toward a position of long-term strength, significance, and financial viability. I work to maintain openness and trust with faculty, staff, students, and interested alumni. I am committed to helping develop faculty and staff toward fruitful careers. I listen well to opposing viewpoints. I seek counsel when I see that difficult decisions must be made. I generally admit when I make mistakes. Finally, I like to work hard and am glad to spend my career contributing to the faculty, staff, and students of New Mexico State University and the people of the state of New Mexico.
