Please come join us on Mondays from 12-1 p.m. in Valentine Terrace Room A (down the stairs). Come and have lunch with fellow math and stats students, majors and professors! Everyone is welcome-you don't need to be a math or stats major. We often chat about math and stats-related topics, but we also talk about lots of other things and it's a great chance to get to know each other. We hope to see you there!
Joe Hogan of Brown University will discuss "Statistical Methods for Improving HIV Treatment Monitoring in Kenya."
In places like the US and western Europe, individuals with HIV who are taking antiretroviral therapy are monitored regularly. This typically involves taking measurements of CD4 cell counts (a measure of immune system function) and HIV viral load (a measure of viral burden) every three to six months.
In low- and middle-income countries, however, this level of monitoring is not typically possible because of limitations in funding, technology and infrastructure. One approach that enables more frequent monitoring is the use of pooling for viral load testing. Individual blood samples are pooled, and a viral load assay is applied to the pooled sample. If viral load exceeds a certain threshold, some or all of the individual samples are tested separately.
We show how statistical methods are used to develop algorithms that lead to the fewest possible tests, thereby saving assays and enabling more testing. Our approach makes use of ideas from machine learning and decision theory.
The Sexuality, Women's and Gender Studies Department is opening its common room as a study space for students every Monday afternoon during the fall semester. Beverages and snacks will be provided. Join us every Monday, except for October 9, which is mid-semester break, and November 20, which is Thanksgiving break.
Joe Hogan is the Chair of Biostatistics at Brown University. As part of my collaborations in HIV, I serve as co-director of the Biostatistics Program for AMPATH, an international consortium of universities in the U.S., Canada and Kenya focused on treatment and prevention of HIV in Kenya, as co-director of the Biostatistics Core for the Lifespan/Tufts/Brown Center for AIDS Research and as PI for the Biostatistics Core for the Brown Alcohol Research Center for HIV. My basic and collaborative research is funded by the NIH and USAID.
I teach both introductory and advanced courses in biostatistics, and supervise 1-2 Ph.D. students at any given time. Between 2003 and 2012 I directed the Biostatistics Graduate Program.
In addition to teaching and research, a significant recent focus involves biostatistics research capacity building at Moi University in Kenya.
Author Ben Hersey will be reading and performing from his book The Autograph of Steve Industry on Monday, November 27 at 8 p.m. at the Zü (26 Snell Street). Hersey is a writer and performance artist. His experimental work draws from a wide variety of sources including contemporary poetry, noise, New England colonial history, genealogy and found texts.
