Experiences in a Ph.D. program in physics are one of a kind, focused on but not limited to science. I will talk about my recent adventures transitioning from an undergraduate at Creighton to finishing Ph.D. work at Oklahoma State University. I will also discuss my research summarized below.

Seminar: Attribution Based Confidence Metric for Neural Networks

Dr. Steven Fernandes and his research team proposed a novel confidence metric called the attribution-based confidence (ABC) metric for deep neural networks (DNNs). The ABC metric characterizes whether the output of a DNN on an input can be trusted. DNNs are known to be brittle on inputs outside their training distribution and are hence susceptible to adversarial attacks. This fragility is compounded by a lack of effectively computable measures of model confidence that correlate well with the accuracy of DNNs, impeding their adoption in high-assurance systems.

Seminar: Nuclear Medicine’s Age of Enlightenment: 2012 to ???

Abstract: The use of radioactive decay and their particulate and gamma-ray emissions in medical imaging and therapy dates back to the late 1930’s with the use of radioactive Iodine. Use of nuclear medicine expanded substantially in the 1960’s with the advent of the gamma camera, and then scientific excitement was boosted again with the invention of positron emission tomography (PET scanning) in the late 70’s. These nuclear technologies demonstrated the ability not to image the anatomy (like x-rays, CT, and later MRI), but to image the actual molecular biochemical underpinnings of diseases, like cancer (the Warburg Effect – look it up!), heart disease, and Alzheimer’s disease.

Clinical use of PET imaging began is the early 1990’s. Creighton University had one of the first clinical PET facilities in the US, opening in 1991 on Dorcas Street, complete with its own cyclotron used to produce radioactive 18F, 11C, 13N, 15O. But challenges to Medicare and insurance reimbursement coupled with regulatory complexities, mostly from FDA, resulted in slow growth, and even stagnation of the field.

Beginning around 2012, through advances in radiation detector technology, computing power, corporate investment, and infrastructure building, nuclear imaging and in particular, radiopharmaceutical therapy have taken off into one of the fastest growing segments of medicine today.
