Dr Farez, please tell us about your research

[MF] In the early stages of my career I was trained and worked mainly in basic MS research involving different biological pathways of relevance in T cell biology and disease activity. I did this both in animal models and patients. As I obtained my training in public health, I started moving from population evidence or findings, to the molecular levels: I love to take a clinical or radiological observation in MS patients and figure a biological explanation all the way to the gene expression level. More recently, I have been using machine learning and artificial intelligence to make those clinical and radiological observations more quantitative and ready to use in translational research.

What achievements have you been most proud of?

[MF] A researcher’s life is full of small victories or achievements (also big disappointments when experiments don’t work!). One achievement I am proud of is that by using the approach of relevant population-level observation, we were able to find an interesting pathway for melatonin-related genes in MS patients. Specifically we showed a seasonal fluctuation in relapses to the exact genetic level. Another great achievement, I would say is that, as a MS researcher, but also as a physician taking care of patients, I was always frustrated with the lack of precision in measuring key parameters such as lesion number and volume and brain volume/atrophy in my patients. How could I say something about treatment efficacy if it was based on a qualitative assessment using a printed MRI scan of 3 × 3 cm? Using AI, we developed, validated, and implemented algorithms to perform such measures with Entelai, a company I co-founded. Now, we can precisely measure brain and lesion volumes in our patients with AI within minutes, and we are using this information not only to make better clinical decisions, but for several translational and collaborative research projects.

Having established yourself in the field of MS research, where do you see it going over the next decade?

[MF] I am happy to see that it is going to a more quantitative and precision medicine-based approach. Artificial intelligence is revolutionizing every field of medicine and it is slowly growing in the MS field and, without doubt, it will occupy the headlines in the next few years in the context of more precise and faster measurements, and helping us in differential diagnosis or to uncover new variants or diseases. Every lab will have a data scientist working with deep learning models and using this powerful tool to answer new questions (in particular for images and genetic data). I do hope that we will also work more on the cause of MS. Without knowing the exact cause we are not getting closer to a cure. We need to understand why people get MS and focus on this. So my wish for the next decade is that funding agencies and donors devote time and resources for this challenge.

One of the key issues faced when developing precision medicine is ensuring that patient recruitment covers all demographics affected by the disease. Helen, please tell us about your research at the moment

[HO] My research focuses on the inequities that exist in MS research and access to specialized MS care. For over a year, I have examined the racial inequalities in phase III trials of MS disease modifying therapies (DMTs) and found that race is underreported in phase III trial publications and that non-White people with MS are largely underrepresented in the participant pools of these trials. Recently, I began a project that seeks to improve the health literacy of the MS patients seen at our clinic by firstly capturing their unique backgrounds, as well as their perspectives on MS and concerns about their disease management. With this insight we hope to develop inclusive culturally-sensitive MS resources that enhance health literacy while allowing people with MS to be confident advocates for their health.

What inspired you to get involved in MS research at such a young age?

[HO] I was first introduced to MS research while working at Penn as a clinical research assistant. My work was mainly behind the scenes–that is, patient scheduling and preparing tubes for collection of biological samples. I enjoyed that work and picked up bits and pieces about what MS is, but I wanted to be more hands-on with the research. When I joined the team at UT, I learned that MS is an incredibly heterogeneous disease–you never know what you’re going to get when a patient walks in the room. I became interested in how this heterogeneity manifests in diverse populations, but was surprised to discover there wasn’t much research on this topic. This segwayed into my work on inequalities in MS research.

Helen, you have already made an impact at such an early stage of your career. What are your aims for the future?

[HO] I plan to attend medical school next year and become a neurologist. I hope that I can continue to do work that highlights the blind spots in MS research and patient care in order to promote inclusive research practices and equitable healthcare access.
