Breakthroughs Blog: Faces of Innovation

Faces of Innovation—a new GHTC project that features scientists on the front lines of research and development on new global health tools and technologies—profiles Dan Littlefield, who we met at the American Society of Tropical Medicine and Hygiene Annual Conference. Dan co-founded a cold-chain engineering company that worked with the Centers for Disease Control and Prevention and the Biomedical Advanced Research and Development Authority to distribute Ebola vaccines for clinical trials in Sierra Leone.My name: Dan Littlefield, MSWhere I work: Modality Solutions LLC I’m funded by: US Centers for Disease Control and Prevention (CDC), Biomedical Advanced Research and Development Authority (BARDA)My research: I’m a principal and one of the founding members of Modality Solutions. We’re a cold-chain engineering company that’s headquartered in League City, Texas, just outside of Houston. We do a lot of work with pharmaceutical and biotech companies to ensure their product, when it gets to the patient, is just as good as when it left manufacturing.Back in 2015, we were contacted by a contractor for the US government because there was a critical need in West Africa to support getting vaccines there as part of a phase III clinical trial that the CDC and BARDA were sponsoring in Sierra Leone for an Ebola vaccine. Motivation: We’re a growing company, we recruit a lot of young engineers, and when I talk to engineers, I find that we all love to do engineering work, but we also all like the direct impact of helping people. And one of the great things about the work we’re doing, especially with the emergency response clinical trials, is that there is a direct tie between the work we’re doing and how we’re saving lives.Why US federal support is critical: First, this is a national security issue because diseases like Ebola are dangerous. They’re dangerous to civilian populations in West Africa and potentially dangerous to US populations as well. And I think there’s an important diplomatic aspect to it. A lot of these countries are allies to the United States, and one of the ways to lift them up and improve living conditions in those countries is to go and do this kind of work. It also provides a stabilizing influence and improves local capabilities as well. That’s one of the things we try to focus on: it’s not about going in and doing the work and leaving, it’s about going in and training the local staff because a lot of very smart pharmacists and medical doctors don’t have a lot of experience dealing with heat transfer and thermal packaging and managing temperature-sensitive pharmaceuticals. If we can go in and transfer that knowledge, it really enhances them and helps them for the future, not just for clinical trials, but even just for standard vaccine strategies and drug treatments.When I’m not in the lab: My hobby is that I work as a reserve patrol sergeant with the Galveston Sherriff’s office. Galveston County is a big county just south of Houston. I work uniform patrol there, and I’m a weapons and tactics instructor for the department—so that fills up the rest of my time.

Faces of Innovation—a new GHTC project that features scientists on the front lines of research and development on new global health tools and technologies—profiles Hannah Wu, who we met at the American Society of Tropical Medicine and Hygiene (ASTMH) Annual Conference, who is working to develop vaccines against the neglected tropical disease schistosomiasis at Brown University.My Name: Hannah WuWhere I work: Brown University Medical School in Providence, Rhode IslandI’m funded by: NIHMy research: We do research on neglected tropical diseases, for malaria and schistosomiasis…I’ve been working on schistosomiasis for a long time. I am lucky enough I can not only work in the lab, but also go to the field to see people. Even though schistosomiasis is more neglected than malaria, there are people in the world suffering from this disease. It’s caused by a trematoda—this is a worm. If we have a vaccine for it, that might be much better to cure the disease or to prevent the disease. So that’s what we are working at. We look at immune mechanisms from the population, and we are trying to find vaccine candidates. For the shistosomisis species, that I am specifically working on…it is also a one health strategy that we should use….We hope that we will have more funding to do other experiments and research on this vaccine, to be available in the livestock.For parasitic diseases, animals are a very important reservoir host. Some people are in touch with animals every day, in their daily life. So we are not only making vaccines for the humans, we can actually make vaccines for, in my case in schistosomiasis, for water buffalo which account for 70 to 90 percent of transmission. So that’s the concept of one health.Motivation: When I was in graduate school, I was not very clear what I wanted to do, but I think I was lucky enough, I got to see the people who had the disease…Because of their everyday life, they have to be in contact with the pathogen, so they cannot really avoid to have the disease, and they don’t have other means….Research has a curiosity I always like. And I was curious about finding new things…but if at the same time I can…contribute to this world by finding a vaccine to help people, that would be great. So that motivates me.Why federal support is critical: We are human beings. We’re not isolated…We care about other people, so that’s one basic reason we can do this research for the world, to improve human health. And I really believe that everyone deserves an opportunity to get health care and to live a more healthy life.When I’m not in the lab: I am involved with my church a lot. Through the church I work with young people. I tell them science is about curiosity. We have the privilege to do science, so we should do real science for real people. We’re not doing science just for the sake of science, we’re doing science for the betterment of human life.

Faces of Innovation—a new GHTC project that features scientists on the front lines of research and development on new global health tools and technologies—profiles Dr. Rohit Ramchandani, who we met at the American Society of Tropical Medicine and Hygiene Annual Conferenc. Dr. Ramchandani does research to innovate global treatment options for childhood diarrhea at the Johns Hopkins School of Public Health in Baltimore, Maryland and the University of Waterloo. My name: Rohit Ramchandani, DrPHWhere I work: Johns Hopkins School of Public Health in Baltimore, Maryland and the University of WaterlooI’m funded by: US Agency for International DevelopmentMy research: My research focuses on diarrhea in children…the second-leading cause of death in children under five globally…These are close to 500,000 deaths that are happening every year, most of which are preventable, and treatable. They’re treatable with medicines, oral rehydration salts [ORS] and zinc. That’s the globally recommended treatment for diarrhea. But the problem is, in many low- and middle-income countries, access to these medicines is not where it should be, particularly in rural communities. So we looked at that issue of access. We did it by leveraging human-centered design approach. And we really focused on the details and the challenges that mothers face treating their children with diarrhea…Our research showed that 40% of the time, mothers are preparing ORS in the wrong concentration: either too diluted, or too concentrated. That can lead to hypernatremia, that can make the diarrhea even worse, or the efficacy gets reduced if it’s too diluted. So we actually worked with a local pharmaceutical company in Zambia to shrink down then size of the ORS sachets—the standard all over the world is a one-liter sachet—we shrunk those down to make 200-mililiter sachets, and then we made the packaging double as a measurement vessel for the right amount of water…One of our key funders during our scale-up phase was USAID—their Discover Health Program. They played a fundamental role in some of the social marketing we were doing as we were scaling up the development of our diarrhea treatment kit.Motivation: There’s just a fundamental issue of justice in the world…We often think of innovation being new product development, high technology, but things like ORS and zinc—innovation can happen really in the delivery side of things. And that’s really where our innovation focused.Why federal support is critical: I think this is low-hanging fruit. Diarrhea, as one of the leading causes of death in the world for children—we have the solutions, we know what to do, and these kinds of innovations can really make a huge difference in saving lives.…[And] there’s a health security argument [to do this work]. The world is getting smaller and smaller every day. We are inextricably linked to one another. When I’m not in the lab: I’m a dad! I’m a dad of two amazing young girls. They inspire me every day. It makes my work in child health that much more meaningful—the inspiration I get from them. I want all parents to have that.

Faces of Innovation—a new GHTC project that features scientists on the front lines of research and development on new global health tools and technologies—profiles Dr. Vinayak Joshi, who we met at the American Society of Tropical Medicine and Hygiene Annual Conference. Dr. Joshi is working on a diagnostic for cerebral malaria with support from the National Institute of Allergy and Infectious Diseases.My name: Vinayak Joshi, PhDWhere I work: VisionQuest Biomedical Inc.I’m funded by: National Institute of Allergy and Infectious Diseases (NIAID), National Institutes of Health (NIH)My research: We are developing a user-friendly, fully automated, and simple-to-use diagnostic for cerebral malaria. Today, cerebral malaria misdiagnosis causes hundreds of thousands of deaths in African children. With improved diagnostic accuracy, we can prevent many of those deaths and associated disabilities. Motivation: My background is in machine learning software development for medical diagnosis. In my PhD research, I developed an algorithm for detecting malarial biomarkers in eyes. Later, I got a chance to visit one of the malaria clinics—and I learned that this particular kind of malaria, cerebral malaria, is one of the largest killers of children in Africa—and I actually witnessed a child’s death which left an impression on my mind. Rather than just focusing on developing an algorithm, I reasoned that developing a tool that would lead to greater accessibility and was affordable to the target population in Africa, would make a significant humanitarian contribution.Why US federal support is critical: One of the major goals of this work is to prevent deaths in young children. For such two- to three-year-old kids—it is one of the biggest global health problems. After a child is affected with cerebral malaria, one needs to take action in 24 to 48 hours, otherwise it results in death. It may not be always reported in the news media, but hundreds of thousands of deaths occur every year from this issue. The death toll and neurological disability in children caused by this disease are important problems, often overlooked by the world outside of sub-Saharan Africa. The United States does a lot of noble work in different countries, in health care, development, other infrastructure, and I think this is one of the problems that should receive more attention. There are many technologies being developed, but developers can’t find the channels to commercialize them, because the African market is not where you make money—you do it for humanitarian purposes. But to develop any product you need money, and I think the US government should look into it. They should support the institutions that produce the tools but have to find sources of funding to commercialize these technologies and make them accessible to the target population.When I’m not in the lab: I like a lot of traveling—it’s one of my hobbies. I don’t particularly like to go to top tourist destinations. I like to explore new, unexplored parts of the country.
