VN-BioStat Program concludes its first year
The Vanderbilt-Nigeria Biostatistics Training Program (VN-BioStat) has concluded its first year. The program, a collaboration between the Department of Biostatistics, the Vanderbilt Institute for Global Health, and Aminu Kano Teaching Hospital (AKTH) in Nigeria, aims to create a cohort of highly skilled Nigerian biostatisticians able to lead and supervise biostatistics activities for HIV research studies in West Africa. Professor Bryan Shepherd is one of the program's principal investigators.
The program’s inaugural fellows were Abdurrahman Abdulhamid (PhD student, mathematics) and Yusuf Ibrahim Ibrahim (PhD student, statistics) from Bayero University Kano in Nigeria. Ibrahim has been working with professor Robert Greevy to study various randomization strategies for a proposed clinical trial in Nigeria. He is also doing a large epidemiology study looking at cytopenia among people with HIV in West Africa. Abdurrahman is looking at the interaction between sickle cell disease and renal disease among people with HIV using a cross-sectional dataset from northern Nigeria. They will continue this work when they return to Nigeria this month while they complete their PhDs at their home institution.

Below, Abdurrahman and Ibrahim share some of their experiences, insights, and advice for future fellows.
Abdurrahman Abdulhamid
Why did you want to join the program?
Assigned and provide analysis support to HIV-related research projects using AKTH data.
What did you like most about the program?
The unique responsibilities and project work associated with this program will absolutely help in developing the skills and experience required to work in a real job.
Did you learn anything that surprised you?
The whole idea of clinical trials, which is in every course in the six courses and weekly seminars, surprised me. Also, the professors are versed in excellent teaching methods.
What will you miss most about the program?
Resources that ease the study, and the prompt assistance from all the members of the Department of Biostatistics.
Do you have any advice for future fellows?
Try to harness the crude knowledge of the great scholars, and have helpful friends among the students.
What are you doing next?
To meet the target of the program by supporting projects at AKTH, and to continue and complete the project I started here and my PhD at Bayero University Kano.
Yusuf Ibrahim Ibrahim
Why did you want to join the program?
I applied this program because, in our country Nigeria, there is relatively a shortage of biostatisticians for the demand of biomedical research, resulting in generally overworked biostatisticians who work on multiple projects at the same time. This program will surely enable me to fill this gap.
What did you like most about the program?
It is great to study biostatistics in one of the focal points of biomedical research in the world. There are many brilliant and dedicated faculty here doing exciting research across a wide variety of critical areas. I admire all the staff of VUMC who are always ready to give you support whenever you need. I do like Nashville as a city. It’s a great place to live, as I am from tropics, however, I like the winter in Nashville. It’s nice seeing the snow for the first time. I will really miss the unique culture and hospitality of the people of Nashville.
Did you learn anything that surprised you?
Absolutely! I have had many wonderful experiences. For instance, before I came here, I looked at the R-software as a very complex and difficult thing to master. However, I was surprised by the ease I am now able to navigate many of its awesome features, courtesy of the fantastic teachers I have had here at Vanderbilt. I have been amazed by how they are able to make the seemingly difficult tasks so easy to master.
What will you miss most about the program?
I will really miss the weekly seminar in the Department of Biostatistics where dedicated academics present interesting research in a wide range of topics and ideas. I will also miss the staff and students of the Biostatistics Department and the Institute for Global Health who supported me intellectually, morally, and socially. Moreover, I will miss playing soccer with Bryan, Dale and others. The time we spent together will forever remain in my memory. Furthermore, I will forever be grateful for the warm hospitality of the people of Nashville.
Do you have any advice for future fellows?
Learning at an advanced level in a new culture/environment could be quite challenging and Vanderbilt, despite its excellence and prestige among the world’s universities, is no exception. I would like to advise the future fellows to prepare well in advance and work hard when they arrive. I have come to realize that the harder I work, the more I like and find ease in what I do. Moreover, they should always be open to meeting and learning from other people.
What are you doing next?
In six months, I just have a modes plan of finishing my PhD in Nigeria, after that, I will continue doing research in Statistics, especially “Causal Inference.” In two years, I wish to come back to one of the academic institutions in the United State as postdoctorate student. In five years, I have more of visionary plan – professionally, I would like to lead my own research group in Nigeria.

Mario Davidson appointed associate vice chair of equity, diversity, and inclusion
Associate professor of biostatistics Mario Davidson has been appointed associate vice chair of equity, diversity, and inclusion (EDI) for the Department of Biostatistics. In this newly created senior leadership role, Davidson will assist vice chair of EDI Leena Choi with promoting awareness and fulfillment of EDI initiatives and standards across the department.

Davidson, the 2022 winner of the Geoffrey David Chazen Award for Innovation in Medical Education, also serves on the board of the Academy for Excellence in Education and as invited faculty for the national Robert A. Winn Diversity in Clinical Trials Program.
The vice chair of EDI position was created in 2020. Choi is the first and current appointee to this role. Under her direction, the department launched its Summer Internship Program for Underrepresented Undergraduates, which has just concluded hosting its second cohort. Choi has also actively provided guidance to department colleagues on EDI training and assessments, particularly in her role as a search committee member. Prospective faculty members must describe their efforts to encourage EDI in research, mentoring/teaching, and community outreach as part of their applications.
Going forward, Choi and Davidson are to be involved with every committee and task force in the department—including the recruitment and advancement of students, trainees, staff, and faculty—with the goal of maximizing opportunities for EDI and guarding against unconscious bias. The mandate for all department members is to be familiar with EDI principles and apply them to all activities.
Additional initiatives in the department include the Diversity and Inclusion Application Fee Waiver for prospective PhD students (see the last section on our Application Process page) and a study group dedicated to Ethical Responsibilities Regarding Race in Research. PhD student Julia Thome is a recipient of the Provost’s Graduate Fellowship, which is offered by Vanderbilt University's Graduate School to incoming U.S. citizens and permanent residents from diverse backgrounds (a $10,000 stipend for five years, supplemental to any other funding offered to the scholar). Professor Bryan Shepherd is co-MPI of the VN-BioStat Training Program; associate professor Robert Greevy and assistant professor Peter Rebeiro serve on its training advisory committee. Abdurrahman Abdulhamid and Ibrahim Yusuf Ibrahim, the first two fellows, are reaching the end of their year in Nashville, and the next two trainees (Rukayya Alkassim and Safiya Sani) are expected to arrive in August.

Chris Slaughter wins 2023 Vanderbilt Epidemiology Teaching Award
Associate professor Chris Slaughter has received the 2023 Vanderbilt Epidemiology Teaching Award. The student-nominated award honors a faculty member for their exceptional effort in training the next generation of epidemiologists in the PhD program.
Students who nominated Chris said that he “really tied all of the concepts we learned in our previous classes together to make them easier to understand,” and that he is “very patient and takes the time to explain concepts and ensure that they are understood.”
Chris received his PhD in biostatistics from the University of North Carolina at Chapel Hill. Since joining the Vanderbilt School of Medicine as an assistant professor in 2007, he has taught Clinical Pharmacology Biostatistics, Statistics for Biomedical Research, Modern Regression Analysis (for which he was a founding instructor), and Design and Analysis of Time to Event Data. He has co-authored almost 200 peer reviewed papers.
Some of Chris’s current research projects include a structure based design of trimer interface epitope focused universal influenza vaccines and therapeutic human monoclonal antibody treatments for filoviruses.
He is also part of the department’s upcoming Coursera program, which will debut within the next year. The program will include a series of courses on applied statistics in biomedical science. Chris is teaching Data Science Workflow for Clinical Trial Data, which will provide students with hands-on experience for successfully working with data collected during a randomized clinical trial.
Other courses in the program will be led by professor Tatsuki Koyama, assistant professor Andrew Spieker, and department chair Yu Shyr.
Congratulations, Chris, and thank you for all your hard work!
