Jason Daniel-Ulloa, PhD, MPH

If public health had a “show your work” requirement (it does), Jason Daniel-Ulloa, PhD, MPH would be the person calmly pointing at the margins:
community partners listed, assumptions challenged, outcomes measured, equity centered. His career sits at a practical intersection of
community-based participatory research (CBPR), Latinx health, and the everyday realities that shape who gets prevention, who gets left out, and why.

Daniel-Ulloa’s work is especially relevant right now because the hardest public health problems aren’t just “medical.” They’re social, historical,
geographic, and deeply human: rural access, language and trust barriers, stigma, discrimination, misinformation, and systems that were not designed
with every community in mind. He has built a body of research and teaching that treats those factors not as footnotes, but as the main text.

From Training to Practice: A Public Health Path Built for the Real World

Daniel-Ulloa’s academic training reflects a classic public health trajectorythen takes a more community-forward turn. He earned a BA in Psychology,
an MPH, and later a PhD in Public Health through the Joint Doctoral Program between San Diego State University and the University of California,
San Diego. That background matters because it blends behavioral science with applied public health: how people make choices, how environments constrain
them, and how interventions succeed (or flop) when they ignore lived experience.

Professionally, he has held faculty roles that combine teaching with research and practice. Across appointments, his focus has stayed consistent:
train the next public health workforce to be self-reflective and effective, and produce research that doesn’t merely study communitiesbut works
with them to co-create solutions.

Core Focus Areas That Show Up Again and Again

Daniel-Ulloa’s portfolio is broad, but it isn’t random. The themes connect like a well-designed subway map: different lines, same destinationhealth
equity. Three areas stand out.

1) HPV Vaccination and Cancer Prevention: When “Available” Doesn’t Mean “Accessible”

HPV vaccination is one of those rare public health tools that is both preventive and powerful: it can reduce infections that lead to several cancers.
Yet uptake in the U.S. has been unevenvarying by gender, race/ethnicity, geography, and other social factors. Daniel-Ulloa has contributed to this
conversation by emphasizing disparities and the way “one-size-fits-all” messaging can fail communities that face structural barriers to care.

His work has also highlighted how rural settings can amplify obstacles: fewer clinics, longer travel distances, less provider availability, and fewer
culturally tailored resources. In rural Latinx communities, these factors often stack togethercreating a situation where prevention tools exist on paper,
but are hard to complete in real life (especially when vaccination requires multiple steps, appointments, or follow-ups).

What makes this research practical is its orientation toward solutions. Rather than framing low vaccination rates as a “knowledge problem” (as if
a pamphlet could fix everything), CBPR approaches push researchers to ask different questions: Who does the community trust? Where do families already
gather? What are the logistical barriers? Which messengers resonate? And how can clinics, schools, and public health agencies coordinate instead of
working in separate silos?

2) Community-Based Participatory Research: Not a BuzzwordA Method with Teeth

CBPR can sound like “being nice to people” if you only read the title. In practice, it’s rigorous work: shared decision-making, mutual accountability,
and designing research that communities actually want (and can use). Daniel-Ulloa has been part of CBPR efforts connected to HIV prevention and
sexual health initiatives, especially those that build on existing strengths such as social networks and community leadership.

A key CBPR insight is that communities often have effective systems alreadyjust not always recognized as “health infrastructure.” For immigrant
and rural Latinx communities, that might mean soccer leagues, churches, mutual aid networks, local organizers, or trusted bilingual advocates. When
public health collaborates with these structures instead of ignoring them, interventions become more culturally congruent and sustainable.

Importantly, CBPR also changes who gets to be an “expert.” Daniel-Ulloa’s work aligns with the idea that community members are not “hard-to-reach”
as much as institutions are often “hard-to-trust.” If you want trust, you build itslowly, visibly, and with receipts.

3) Latino Men’s Health, Masculinity, and Harm Reduction in Everyday Life

Another signature thread in Daniel-Ulloa’s work is Latino men’s health, including how masculinity norms influence health behaviors. In rural
immigrant contexts, health decisions can be shaped by expectations about toughness, self-reliance, and providing for familysometimes at the cost of
preventive care, mental health support, or timely clinic visits.

This line of research matters because it shifts public health away from blaming individuals (“Why don’t they just go to the doctor?”) and toward
understanding social scripts (“What does seeking help mean in this context?”). When interventions account for identity, discrimination, economic pressure,
and belonging, they can support healthier behavior without shaming the very people they aim to serve.

Daniel-Ulloa has also worked on initiatives with Latino college men, focusing on healthy masculinity and the prevention of gender-based violence.
Here again, the throughline is community-informed change: programs that take culture seriously, address power dynamics explicitly, and build skills for
respectful relationships and safer communities.

Teaching Philosophy: Decolonized Frameworks, Storytelling, and “Positionality Checks”

Many faculty can teach content. Fewer teach students how to think about power, history, and the unintended consequences of “help.”
Daniel-Ulloa’s teaching approach has been described as blending CBPR training with decolonized teaching frameworksencouraging students to reflect on
positionality (who they are in relation to the communities they serve), to question ahistorical solutions to systemic inequities, and to recognize
community strengths rather than arriving as problem-solvers with a prewritten script.

He also emphasizes storytelling as a public health toolnot for fluff, but for clarity. Data can show patterns, but stories often explain mechanisms:
why someone skipped a follow-up dose, why a clinic feels unsafe, why a “free” service still costs too much in time, transport, or dignity.

If you’ve ever sat through a lecture where “social determinants of health” becomes a phrase people nod at without changing anything, this kind of
pedagogy is the antidote. It turns determinants into decisions: what do you measure, whom do you involve, how do you fund, and what do you change
when the community says your idea is not working?

What His Work Suggests About Doing Public Health Better

Daniel-Ulloa’s career offers a practical blueprint for how to do equity-centered public health without turning it into a slogan:
you pair rigorous methods with humility, you treat community partnership as essential infrastructure, and you design interventions that respect context.

Concrete lessons practitioners can use

• Start with relationships, not recruitment. If the first time a community sees you is when you need survey responses, you’re already late.
• Build linkages, not islands. Vaccination campaigns work better when clinics, schools, faith organizations, and local advocates coordinate.
• Design for completion, not initiation. One dose is progress; a completed series is protection. Programs should remove barriers to follow-up.
• Address identity directly. Masculinity norms, discrimination, and migration stress can shape health behaviors as much as cost or distance.
• Measure what matters to the community. Outcomes should include trust, cultural fit, and sustainabilitynot only short-term numbers.

These principles are especially useful for health departments and clinics trying to improve prevention in underserved areas. They’re also relevant for
educators who want students to graduate with more than jargonstudents who can listen, collaborate, and build programs that actually work outside a textbook.

Why This Profile Matters for Readers Outside Academia

You don’t need a PhD to see the value in Daniel-Ulloa’s approach. If you’re a parent navigating vaccines, you benefit when systems are coordinated and
culturally competent. If you’re a clinician, you benefit when community partnerships help you reach patients with fewer missed appointments and better follow-up.
If you’re a public health student, you benefit from training that prepares you for the ethical and relational complexity of real-world work.

And if you’re simply a person living in a community that has been “studied” a lot but helped very littlethis approach is a reminder that research can be
done differently. Not perfectly. Not instantly. But differently, and better.

Experience in the Field: What Work Like This Actually Looks Like (500+ Words)

It’s easy to talk about “health equity” in a conference room where the coffee is plentiful and the Wi-Fi never drops. It’s harderand more meaningful
to do equity work in places where access is limited, trust has been bruised, and the nearest clinic might be a long drive away. Experience-informed public
health work, like the kind associated with Daniel-Ulloa’s focus areas, often unfolds in small, unglamorous moments that rarely make it into headlines.

Picture a rural community where families have heard about the HPV vaccine, but the path from “heard” to “completed the series” is a maze. Maybe parents
are juggling multiple jobs. Maybe transportation is unreliable. Maybe clinic hours overlap with work hours, and missing work means missing rent. Maybe a
family worries about paperwork, language barriers, or being treated with suspicion. In these realities, the obstacle isn’t simply awarenessit’s friction.
A CBPR mindset asks: where is the friction, and who feels it most?

The practical work often starts with listening sessions that feel less like “research” and more like community problem-solving. Stakeholders might include
school staff, local health departments, church leaders, parents, and clinic teams. The goal is not to convince everyone to adopt a prepackaged program;
it’s to co-design something that fits. That may mean partnering with a mobile clinic, coordinating vaccination events with existing community gatherings,
or identifying trusted messengers who can speak in culturally resonant wayswithout sounding like they’re reading from a script written three states away.

One of the most experience-shaped lessons in HPV prevention work is that logistics can be destiny. If the second dose requires a separate appointment that
is hard to schedule, completion rates suffer. So public health teams look for ways to make the “healthy choice” the “easy choice”: reminder systems that
don’t assume stable phone numbers, walk-in opportunities, bilingual materials that respect different literacy levels, and partnerships that keep families
from needing to navigate multiple agencies on their own. Even small shiftslike simplifying scheduling, adding weekend hours, or placing services closer to
where people already arecan change outcomes.

Now layer in the masculinity-and-health lens. In some communities, the expectation to be “strong” can translate into delaying care, minimizing symptoms,
or seeing prevention as unnecessary until something is obviously wrong. Programs that aim to support Latino men’s health have to thread a needle:
respecting cultural identity while expanding what “strength” can mean. Experience-based approaches often reframe help-seeking as responsibility, protection,
and leadershipvalues that resonate. Instead of saying, “Stop being macho,” a more effective message might be, “Being there for your family means taking
care of yourself, too.” It’s not a clever slogan; it’s a culturally aligned reframe.

The same principle applies to sensitive topics like sexual health and HIV/STI prevention. Community-based interventions frequently succeed when they build
on social networks people already trustteammates, peer leaders, and community connectors. The work is not about parachuting into a community with a lecture;
it’s about building local capacity so information travels through relationships, not just flyers. And capacity-building takes time: training peer leaders,
creating feedback loops, adapting materials, and being willing to revise the plan when community members say, “That part won’t work here.”

Finally, there’s the teaching sidethe part that shapes what the next generation does after graduation. Experience-oriented public health education asks
students to practice “positionality checks” before they design solutions. Who benefits from this program? Who might be burdened by it? What assumptions
are baked into the intervention? What history exists between institutions and communities? Students learn that good intentions are not a strategyand that
communities are not blank slates waiting to be improved. They are partners with knowledge, priorities, and power that deserve respect.

In other words, experience-related public health work looks like coordination, humility, and iteration. It looks like building bridges between clinics and
community organizations, and then maintaining those bridges when the grant cycle ends. It looks like measuring outcomes while also measuring trust.
And it looks like remembering that the point of research is not a publicationit’s a healthier, more just world that communities can recognize as their own.
