Raise the Line

We've had many conversations on Raise the Line about the challenges of health communication in today's world of information overload, but none of our guests have the kind of expertise Dr. Tesfa Alexander has acquired in a career that has taken him from Madison Avenue to the halls of government and academia. From guiding tobacco education research at the FDA to leading public health initiatives at MITRE, Dr. Alexander has developed a deep understanding of the science and strategy behind effective health communication. “Successful campaigns keep the long game in mind where you want to develop a lasting relationship with your target audience,” he tells host Lindsey Smith. That relationship needs to be built on understanding culture, beliefs, priorities and daily realities, and only then can you develop messaging that will resonate, he explains. Dr. Alexander also believes these relationships can be leveraged to help people sort out facts from misleading or inaccurate claims. “I strongly recommend shifting our focus from combating misinformation head on, and instead working with the communities who we are seeking to serve.”

This fascinating look at communication science also covers:

Tune in as Dr. Alexander unpacks what it takes to influence beliefs, and ultimately behaviors, in an era defined by misinformation and institutional mistrust.

We’re marking Rare Disease Month 2026 by highlighting the powerful story of Shanthi Hegde, a young patient advocate working to transform how bleeding disorders are understood, treated, and supported. This work is fueled by her own arduous journey with two rare bleeding disorders and immune dysregulatory syndrome, and an extended diagnostic odyssey marked by dismissal, underdiagnosis, and structural bias. “I was told many times by many providers that these disorders are not common in Indians and that my bruises were there just because I'm brown.” Admirably, Shanthi pushed past this mistreatment, advocated for her medical needs, and devoted herself to tackling a range of issues confronting rare disease patients from mental health access to affordable drug pricing to research equity.

In this remarkable Year of the Zebra conversation with host Lindsey Smith, you’ll also learn about:

Join us for a conversation that connects patient voice to system change, and explores what real equity for rare disease communities will require.

Few issues have tested public trust in medicine as deeply as vaccines, and few individuals have influenced that dialogue more than Dr. Paul Offit, director of the Vaccine Education Center at the Children’s Hospital of Philadelphia and a longtime member of the FDA’s Vaccine Advisory Committee. In this timely and candid interview with Raise the Line host Lindsey Smith, Dr. Offit points to this year’s severe flu season and a resurgence of measles as alarming proof points of how a changing federal perspective on vaccine policy is having a real impact on public health. “You’d like to think you can educate about the importance of vaccines, but I fear at this point the viruses themselves are doing the educating.” 

In this wide ranging discussion, Dr. Offit also addresses: 

• The rigorous and painstaking process of developing vaccines, based on his experience co-inventing the rotavirus vaccine. 
• Shifting levels of public trust in scientific organizations. 
• Promising innovations in vaccine development. 

Don’t miss this deeply-informed perspective on the interplay of science, policy, and public education, and his encouraging message to young clinicians about managing the current challenges in public health.

“I do not believe we should be testing to test. We have to know, is this test going to change management and is it going to make a difference,” says pediatric allergist-immunologist Dr. Zachary Rubin. His knack for providing that sort of straightforward guidance explains why Dr. Rubin has become a trusted voice on allergies, asthma, and vaccines for his millions of followers on social media platforms. It’s also why we couldn’t ask for a better guide for our discussion on the rise in allergies, asthma, and immune-related conditions in children, and how families can navigate the quickly evolving science and rampant misinformation in the space. On this episode of Raise the Line, we also preview Dr. Rubin’s new book, All About Allergies, in which he breaks down dozens of conditions and diseases, offering clear explanations and practical treatment options for families. 

Join host Lindsey Smith for this super informative conversation in which Dr. Rubin shares his thoughts on a wide range of topics including: 

• What’s behind the rise in allergic and immune-related conditions.
• Tips for managing misinformation, myths and misunderstandings. 
• How digital platforms can be leveraged to strengthen public health.
• How to build back public trust in medicine.

“Climate change is the biggest health threat of our century, so we need to train clinicians for a future where it will alter disease patterns, the demand on health systems, and how care is delivered,” says Dr. Sandro Demaio, director of the WHO Asia-Pacific Centre for Environment and Health, underscoring the stakes behind the organization’s first regionally-focused climate and health strategy. The five-year plan Dr. Demaio is leading aims to help governments in 38 countries with 2.2 billion people manage rising heat, extreme weather, sea-level change, air pollution and food insecurity by adapting health systems, protecting vulnerable populations, and reducing emissions from the healthcare sector itself. In this timely interview with Raise the Line host Michael Carrese, Dr. Demaio draws on his experiences in emergency medicine, global public health, pandemic response and climate policy to argue for an interconnected approach to strengthening systems and preparing a healthcare workforce to meet the heath impacts of growing environmental challenges. This is a great opportunity to learn how climate change is reshaping medicine, public health and the future of care delivery.

We have a special episode of Raise the Line on tap today featuring the debut of host Dr. Parsa Mohri, who will now be leading our NextGen Journeys series that highlights the fresh perspectives of learners and early career healthcare professionals around the world on education, medicine, and the future of care. Parsa was himself a NextGen guest in 2024 as a medical student at Acibadem University in Turkey. He’s now a general physician working in the Adult Palliative Care Department at Şişli Etfal Research and Training Hospital in Istanbul.  Luckily for us, he’s also continuing in his role as a Regional Lead for the Osmosis Health Leadership Initiative (OHLI). For his first guest, Parsa reached out to a former colleague in the Osmosis family, Negeen Farsio, who worked with him as a member of OHLI’s predecessor organization, the Osmosis Medical Education Fellowship. Negeen is now a graduate student in medical anthropology at Brunel University of London, a degree which she hopes will inform her future work as a clinician. “Medical anthropology is a field that looks at healthcare systems and how human culture shapes the way we view different illnesses, diseases, and treatments and helps you to see the full picture of each patient.” You are sure to enjoy this heartfelt conversation on how Negeen’s lived experience as a patient and caregiver have shaped her commitment to mental health and patient advocacy, and how she hopes to marry humanity with medicine in a world that yearns to heal.

New research is transforming the outlook for cervical and uterine cancers -- two of the most serious gynecologic malignancies worldwide – and we’ll be hearing from one of the people shaping that progress, Dr. Mary McCormack, on this episode of Raise the Line. From her perch as the senior clinical oncologist for gynecological cancer at University College London Hospitals, Dr. McCormack has been a driving force in clinical research in the field, most notably as leader of the influential INTERLACE study, which changed global practice in the treatment of locally advanced cervical cancer, a key reason she was named to Time Magazine’s 2025 list of the 100 most influential people in health. “In general, the protocol has been well received and it was adopted into the National Comprehensive Cancer Network guidelines which is a really big deal because lots of centers, particularly in South and Central America and Southeast Asia, follow the NCCN’s lead.”In this conversation with host Michael Carrese, you’ll learn about how Dr. McCormack overcame recruitment and funding challenges, the need for greater access to and affordability of treatments, and what lies ahead for women’s cancer treatment worldwide.

“The world is a very volatile place, with currently 110 conflicts globally, and yet healthcare staff in the hospitals, even here in London, are not prepared to be the only clinician who can help in a crisis or hostile setting,” says Dr. James Gough, CEO of the David Nott Foundation, which equips providers with the skills and confidence needed to function in war and other extraordinary situations. A former British Army doctor injured in Afghanistan, Gough brings lived experience as well as a background in tech to his current role at the Foundation, which itself is anchored in decades of field work amassed by its namesake, a renowned war surgeon. As Dr. Gough points out to host Lindsey Smith, the cause could be helped by augmenting medical school curricula, but in the meantime, the Foundation is filling the knowledge gap by using prosthetics, virtual reality simulations and cadavers to train a broad swath of health workers including surgeons, anesthetists, and obstetricians. Tune in to this important Raise the Line conversation as Dr. Gough reflects on the strengths and weaknesses of NGOs in doing this work, his plans to expand the Foundation’s footprint in the US, and the gratifying feedback he’s received from trainees now operating on the frontlines in Ukraine and elsewhere.

“People are not looking for a perfect, polished answer. They're looking for a human to speak to them like a human,” says Jessica Malaty Rivera, an infectious disease epidemiologist and one of the most trusted science communicators in the U.S. to emerge from the COVID-19 pandemic. That philosophy explains her relatable, judgement-free approach to communications which aims to make science more human, more accessible and less institutional. In this wide-ranging Raise the Line discussion, host Lindsey Smith taps Rivera’s expertise on how to elevate science understanding, build public trust, and equip people to recognize disinformation. She is also keen to help people understand the nuances of misinformation -- which she is careful to define – and the emotional drivers behind it in order to contain the “infodemics” that complicate battling epidemics and other public health threats. It’s a thoughtful call to educate the general public about the science of information as well as the science behind medicine. Tune in for Rivera’s take on the promise and peril of AI-generated content, why clinicians should see communication as part of their professional responsibility, and how to prepare children to navigate an increasingly complex information ecosystem.
