Point-of-care diagnostics for
Welcome to Lutz Lab
Simple phenomena + clinical need + real-world constraints
As bioengineers we seek to apply scientific understanding to develop technology for improving human health. Our work is defined by manipulation of simple physical and biochemical phenomena to create devices for unmet clinical needs, and attention to real-world constraints improves the chances that our work will impact patients. The interplay between science, technology, clinical need, and real-world constraints creates a puzzle that requires a disciplined form of creativity and invention.
Positions available with Lutz Labs
The Lutz group is recruiting postdoctoral researchers and research engineers to develop novel point-of-care diagnostics for global health and home testing. We have multiple projects in areas of HIV, respiratory infection (including Covid-19), and other infectious diseases. We are looking for strong thinkers who can contribute in the following areas:

Nuttada Panpradist Receives UW College of Engineering Award
June 7Congratulations to Nuttada for being recognized for outstanding contributions to UW Bioengineering research! The UW College of Engineering Awards acknowledged the extraordinary efforts of the college’s teaching and research assistants, staff and faculty members.Nuttada Panpradist’s impressive academic career includes 13 publications, 17 conference proceedings, and four patent applications. Her simple point-of-care tests detect HIV genetic mutations to help doctors prescribe non-resistant drugs. She designed rapid lab tests for COVID-19 and devices to ensure patients are taking their TB medication. She has collaborated with various researchers on COVID-19 projects such as developing new methods to detect SARS-CoV-2 in Seattle to validating point-of-care tests in pediatric clinics. As a mentor, Panpradist connects undergraduate students with research projects that match their interests. All her students have received research scholarships and are named as co-authors and co-inventors of patents. “Nuttada has gone above and beyond to foster our new collaboration; beyond her scientific acumen, she is an attentive and professional partner, mature beyond her years, conscientious, flexible, able to balance multiple responsibilities, and has an impressive work ethic.”
05/26Amy passed her Ph.D. defense, titled "Improving diagnosis of tuberculosis from urine cell-free DNA." Congratulations Amy!"02/01Nuttada's paper from 2014 on swabs for point-of-care testing is getting a lot of attention lately. She characterized the release of samples from different nasal swab types, including the effect of manual agitation and a novel design for flow through swabs - very relevant today for Covid testing. She is working on a follow-up paper - coming soon!
03/27The Lutz group is recruiting for postdoctoral researchers and research engineers to develop novel point of care diagnostics for global health and home testing. We have multiple projects in areas of HIV, respiratory infection (including Covid-19), and other infectious diseases. We are looking for strong thinkers who can contribute in the following areas:

Congratulations to Doan and Ian on graduating. Ian made it to coveted Husky 100 and is heading to MIT for graduate school. Doan will be working with Physio Control in Redmond WA. Good luck to you both.
Congratulations to Nuttada and Rahil to make it final round of APF Student Technology Prize. Both are independently getting $10k to further their research. Final proposals are due Aug 29.
Congratulations to Annie on receiving Mary Gates Research Scholarship!
Nuttada and Dr. James Lai (our collaborator on the OLA-Simple Project) wrote a chapter on point-of-care diagnostics as part of the book titled "Biomaterials Nanoarchitectonics" edited by Mitsuhiro Ebara. The book has just been published and now available at Elsevier website and can be downloaded via the UW library.
