1. 1 Britton Chance: his life, times, and Legacy My career path before, during, and after being trained under BC (1992-1996) Hanli Liu, Ph.D. Joint Program in Biomedical Engineering The Univ. of Texas at Arlington and Univ. of Texas Southwestern Medical Center at Dallas

2. 2 Before March 1992 A graduate student in Physics at Wake Forest University; A very good Ph.D student with 7 papers ( not 1st author) but did not know how to do research During March meeting in 1992: In front of a poster, meet a “crazy” professor; shooting light to human head ? Maybe he needs some help with research?

3. 3 Who is Britton Chance? World renown scientist in biophysics/biochemistry!! 80 years old?! In Summer of 1992, Joined JF Enriched research environment; Weekly seminars given by world- class scientists; Extraordinary networking collaboration opportunities; Translation studies with clinicians; Survival principle with his patience and trust.

4. 4 First lesson learned: July 4, 1992 Getting ready to sail in the afternoon; Really got out from his house at 9:00 pm!! Be brave to explore new adventure! New journey to learn new knowledge!

5. 5 Am I smart enough to be there without correct training? Second lesson learned: Working with very bright and smart people, i.e., facing competition. How to survive at JF and working in parallel with Arjun’s group, i.e., David and Maureen? After I got into BC’s lab in Summer 1992, 5 Medical Japanese doctors; 20 high school students; 5+ post doctoral fellows; 10+ electrical engineers; 10+ graduate students; countless visitors/collaborators.

6. 6 Britt gave me enough time and trusted me for about 2 years before I really became self- confident or found my survival methods: Find what I am good at and explore unique and collaborative opportunities.

8. 8 Fall 1996, I took the position at Univ. of Texas at Arlington; Had only $20K for Start-up, thinking I take my risk as a new journey. Nov. 1996, Britt was coming to Arlington, and Ron was very nicely hosted the dinner and took this very valuable photo. Whenever Britt came to Dallas, he called me and helped me with a larger or broader network.

9. 9 I took my naïve initiation with 20K and started with a neurosurgery navigation system to guide functional neurosurgery. This led to the Whitaker fund and my first R01 grant. Tumor oximetry by NIR spectroscopy collaboration with Dr. Mason from UTSW to study tumor vascular dynamics for prognosis of breast cancer therapy. This led to four different kinds of DoD Breast Cancer Research Funding.

10. 1010 I found a group of mathematicians and a clinical program, stroke and its treatment. Then, worked with them, leading to a R21/R33 for a 5-year study. Urethr a I wish to go beyond breast cancer detections. So, took a few years to find a urologist and surgeon to explore the optical properties of human prostate. This study led to two DoD prostate cancer research funding, and one R01 funding.

11. 1 I still wish to study the human brain, but I could not do it earlier. With a STARS program from Texas, I obtained $500K for instrument, then, with UTSW/UTD, EarMark fund. CW-6 DYNOT

12. 1212 To predict therapy outcome for children with cerebral palsy. Leading to a recent R01 funding. ~ 30 subjects Cephalogics high- density brain imager  To detect pain or pain intensity;  To study cognitive function during psychological tests;  To quantify risk factors that can be used for high-risk populations;  To study cognitive functions for PTSD (post traumatic stress disorder).

13. 1313 To detect cognitive function To detect pain or pain intensity
