Pablo LaValle retiring this spring

Our longtime Instructional Laboratory Supervisor, Pablo LaValle, will be retiring this April.| Short Read

Our longtime Instructional Laboratory Supervisor, Pablo LaValle, will be retiring this April. He has managed the ChE labs since 1987, so many of you know how special Pablo is to our undergraduate program. During his years of exceptional service in the department, Pablo has earned the respect of both faculty and students, and has received every award a staff member can be given at Michigan. Look for an article about Pablo and his many contributions to the department in the newsletter this summer.

We are compiling a memory book to present to Pablo this spring. If you would like to send us a greeting, congratulations, or a thank you note, or if you have a story you would like to share about him, please send them to Sandy Swisher, at by April 8.

If you might be interested in being the next Pablo, or know someone who you think would be a great fit for the position, please visit  the job posting at

The electrons absorb laser light and set up “momentum combs” (the hills) spanning the energy valleys within the material (the red line). When the electrons have an energy allowed by the quantum mechanical structure of the material—and also touch the edge of the valley—they emit light. This is why some teeth of the combs are bright and some are dark. By measuring the emitted light and precisely locating its source, the research mapped out the energy valleys in a 2D crystal of tungsten diselenide.

Mapping quantum structures with light to unlock their capabilities

Rather than installing new “2D” semiconductors in devices to see what they can do, this new method puts them through their paces with lasers and light detectors. | Medium Read
