Ormachea Completes Postdoctoral Appointment

October 31, 2021

Dr. Juvenal Ormachea has completed his postdoctoral appointment in the Parker Lab. He will be moving to the the state of Washington and will join Verasonics, Inc. as a research scientist. Juve joined the lab as a PhD candidate from Ponfificia Universidad Católica del Perú and successfully defended his PhD thesis in January of 2020. He then began working as a postdoctoral associate in the lab. Juve has been a tremendously successful and productive PhD student and postdoctoral researcher. He will be missed, and we wish him the best of luck in his new career!
