Trained as an immunologist, Dr. Ontiveros is interested in a multi-disciplinary approach to research that blends his expertise with concepts and tools from the fields of bioengineering, cell biology, microbiology and remote sensing. He joined the faculty at St. John Fisher College (now University) in 2012, after completing postdoctoral fellowships at the U of Massachusetts and the U of Rochester. In 2018 he received tenure and promotion to Associate Professor and in 2019 he and his wife founded PETL Fluidics to provide consulting services to industrial and academic research laboratories and to develop STEM education kits. During the summers of 2018, 2019 and 2022 he conducted research at the U of Notre Dame as a visiting and adjunct professor in the College of Engineering. In 2021 Dr. Ontiveros received the St. John Fisher College Trustees' Award for Distinguished Scholarly Achievement.

"The central point of a college education is to seek truth and to learn the skills and acquire the virtues necessary to be a lifelong truth-seeker. Open-mindedness, critical thinking, and debate are essential to discovering the truth.... Since no one wants to be or be thought of as a bigot or a crank, the easy, lazy way to proceed is simply by falling into line with campus orthodoxies. Don’t do that. Think for yourself.”

Elisabeth Dona

Elisabeth joined the laboratory in her junior year as a biology major. After a short stint with bioprinting, she will be working with PETLs in the Spring and Fall of 2022. A STEM and Honors student, she is interested in pursuing a career in the medical field after college. 

A Biochemistry major, Audrey is a Science Scholar at Fisher and during the Spring of 2021 she has been gearing up for taking over our diagnostics project with U of R. Besides reading up on nano membranes and pre-step filtration methods, Audrey has begun to build chips; She attended a NSF-REU Program in Alabama the summer of 2021 and is now a doctoral student in biochemistry at the University of Delaware.

Jackie is a rising junior biology major planning on attending graduate school. She joined the lab in January of 2020 to develop novel PETL microfluidics for cell culture experiments. In a few weeks she became an expert PETL manufacturer, and will be designing and building microfluidic devices as a Summer Scholar. A member of the Tri Beta Biology Honors Society she is also a member of Fisher's tennis team.

Jackie is now pursuing a MS in Parasitology at the U of Albany.

Erik is a junior biology major and a member of the Science Scholars program.  After a short stint with PETLs he is now working on micro- milling of microfluidic devices.  In the recent past he took the opportunity of joining Fisher chemistry professor A. Ignatchenko at Oak Ridge National Lab for a summer research internship. He is now pursuing a MS in medical sciences.

Alex joined the lab in 2019 when he became a Summer Research Fellow funded by SJFC and the University Radiation Medicine foundation.  With this support he traveled to the U of Notre Dame to join Dr. Ontiveros and his collaborators in the Zartman Laboratory.  He worked in two distinct projects involving PETL microfluidics: 1. Use of microfluidics for size-based separation of microparticles, and 2. Design and fabrication of PETL microfluidics to for electrophoresis. He continues to work in the laboratory until his graduation in December of 2019, working on 3D printed adaptors for smart phone imaging and two manuscripts. He is currently completing a doctoral program in podiatry in Iowa. 

Together with Alex, Fabio joined the lab as a Summer Research Fellow and also traveled to the U of Notre Dame in 2019. His project consisted in the design and fabrication of a "double compressor" device, in which D. melanogaster embryos are contained in micro channels with flexible walls. Pneumatic actuation exerts controlled pressure on the specimens while molecular events (e.g. calcium release) are imaged using confocal microscopy. Fabio graduated in December of 2019 with a degree in Biology and together with Alex he is now enrolled in a doctoral program in podiatry in the midwest.

Nick is a junior in the Biology program and is interested in attending Medical School after Fisher. He is part of the Bacteria Remote Sensing Project, working in collaboration with Dr. Herman in our department. His main task is to determine species identities in our library of more that 1000 bacterial isolates. He spent the Spring of 2020 studying abroad in Costa Rica. Nick also did an enormous amount of work processing the data and finding relationships between species and locations. He is the main drive behind getting ready a manuscript for submission. Nick is now a medical student in North Carolina.
