University of Auckland Pacific Genetics Scholar Dougie 'Atiola Driven to Improve Community Health Outcomes

Dougie 'Atiola's path to becoming a leading voice in Pacific genetics research at the University of Auckland exemplifies how personal experiences can fuel groundbreaking scientific inquiry. As a doctoral candidate in the Department of Molecular Medicine and Pathology, 'Atiola is deeply immersed in studying genetic variants unique to Polynesian populations and their links to metabolic conditions. His work, conducted at the prestigious Liggins Institute, promises to unlock new understandings of why Pacific peoples in New Zealand face disproportionate health challenges, while also highlighting protective factors that could redefine treatment approaches.

From a young age, 'Atiola witnessed the limitations of healthcare firsthand. At 14, he was hospitalized with meningitis in Tonga, an experience that ignited his passion for biomedical science. This pivotal moment, combined with a family legacy of educators—his parents taught at high school and tertiary levels—steered him toward a career aimed at serving his community. Relocating to Aotearoa New Zealand after graduating from Tupou College in 2012, he began his higher education journey with a Certificate in Health Sciences at the University of Auckland, followed by a Bachelor of Science in Biomedical Science and a Master's with First Class Honours.

From Patient to Pioneer: 'Atiola's Introduction to Research

The turning point came during his undergraduate years when Associate Professor Troy Merry introduced him to the CREBRF Study, now evolved into the Deep Phenotype Study. This project investigates how genes unique to Māori and Pacific people influence energy use and storage. 'Atiola recalls, "I realised that becoming a doctor isn’t the only way to improve health outcomes for our people. Research is another powerful pathway." This realization shifted his focus from clinical medicine to the lab, where he could address root causes through genetics.

Today, as a Pacific Genetics Scholar, 'Atiola delves into the molecular roles of population-specific mitochondrial variants in metabolic disease. Polynesians carry the CREBRF rs373863828 variant at frequencies up to 30 percent, paradoxically linked to higher body mass index (BMI) but reduced risk of type 2 diabetes and gestational diabetes mellitus. His PhD explores these mechanisms, aiming to explain why Pacific individuals might gain weight more readily yet experience metabolic protection—a finding with profound implications for personalized medicine.

The Liggins Institute: A Hub for Lifespan Health Research

Housed within the University of Auckland's Faculty of Medical and Health Sciences, the Liggins Institute stands as New Zealand's foremost center for investigating lifelong health determinants. From pre-conception influences to aging, its investigator-led programs tackle complex issues like metabolic disorders, which disproportionately affect Pacific communities. 'Atiola's research aligns perfectly with the institute's mission, leveraging advanced phenotyping to map genetic-environmental interactions.

The institute's collaborative environment fosters interdisciplinary work, drawing on expertise in genomics, epidemiology, and clinical translation. For Pacific scholars like 'Atiola, it provides not just facilities but a platform to lead studies centered on underrepresented populations. Ongoing projects, including those on immuno-metabolic effects of unique Māori and Pacific genetic variants, underscore UoA's commitment to equity-driven science.

Supervisory Team and Mentorship Excellence

'Atiola benefits from a world-class supervisory team: Professor Peter Shepherd, an expert in metabolic signaling; Associate Professor Troy Merry, who sparked his research interest; Dr. Chris Hedges, specializing in mitochondrial biology; Dr. Natalie Netzler, focused on viral genetics; and mentor Dr. Chris Puli‘uvea, his former teacher turned immunologist. This guidance ensures rigorous, culturally attuned research.

Mentorship extends beyond academics. Puli‘uvea, from Tonga, exemplifies Pacific success in science, inspiring 'Atiola to pay it forward. "Representation matters," he says. "Māori and Pacific voices don’t just belong in these spaces—we should be leading in them." He actively mentors other Pacific students, challenging the notion that health careers are limited to medicine or nursing.

Pacific Health Disparities in Aotearoa: The Urgent Context

Pacific peoples in New Zealand, comprising about 8.7 percent of the population, endure stark health inequities. Diabetes prevalence is roughly three times higher than for Europeans, obesity rates exceed 70 percent in adults, and life expectancy lags by approximately six years. Cardiovascular disease, gout, and chronic kidney disease also burden communities disproportionately.

These gaps stem from a mix of socioeconomic factors, access barriers, and genetic predispositions shaped by evolutionary history—such as the thrifty gene hypothesis for Pacific islanders adapted to feast-famine cycles. Recent NZ Health Survey data from 2026 reveals regional variations: higher smoking and psychological distress in Pacific groups, underscoring the need for targeted interventions. Genetics research like 'Atiola's offers hope by identifying protective alleles amid vulnerabilities.

Unpacking the CREBRF Paradox: Key Findings and Implications

The CREBRF gene variant (rs373863828 A allele) exemplifies genetic complexity. Studies from UoA and collaborators show carriers have 1.3-1.5 kg/m² higher BMI yet 20-30 percent lower type 2 diabetes risk. This 'obesity paradox' suggests enhanced energy partitioning—more fat storage but better insulin sensitivity.

'Atiola's work builds on this, using cellular models to probe mitochondrial function. Preliminary insights could inform therapies sparing lean mass while mitigating cardiometabolic risks. For NZ's Pacific population, where metabolic syndrome affects over half of adults, such discoveries pave the way for precision health strategies. Explore the CREBRF Study details.

Family as Foundation: The 'Atiola Village

Success rarely happens in isolation, and for 'Atiola, family is his anchor. His wife Losaline provides unwavering support through PhD rigors, while his extended whānau from Tongan villages Hofoa, Kolomotu‘a, Kolonga, and Vaini cheers from afar. This 'strong village' embodies Pacific values of collective upliftment, mirroring the communal approach needed in research addressing group-specific health.

In higher education, such networks are vital for Pacific students facing isolation. UoA's Pasifika programs, including peer mentoring and cultural events, replicate this support, boosting retention and success rates.

Mentoring the Next Generation at University of Auckland

Beyond his thesis, 'Atiola champions Pacific entry into research. He shares his story to demystify academia: "Research is another way to make real change, and our perspectives are needed." UoA facilitates this through scholarships like the Pacific Academic Excellence Scholarships (up to $20,000 first year) and targeted PhD funding.

These initiatives have increased Pacific PhD completions by 25 percent over five years, fostering a pipeline of leaders. Programs emphasize cultural safety, whakapapa verification for eligibility, and community engagement, ensuring research benefits flow back to Pacific communities.

Broader NZ University Efforts in Pacific Health Research

UoA leads, but peers contribute. The University of Otago's Pacific Islands Families Study tracks cohort health, while Massey explores evolutionary metabolic adaptations. Collaborations via the Health Research Council fund projects like immuno-metabolic effects of Pacific variants.

Nationally, initiatives like Te Pūnaha Mātai address data sovereignty, prioritizing Pacific-led genomics. These align with Te Tiriti o Waitangi principles, promoting equitable partnerships and reducing disparities through evidence-based policy.

Future Horizons: Pacific-Led Science Across the Moana

As 'Atiola nears PhD completion, his vision expands: securing grants for academia, leading Pacific-focused labs, and bridging Moana communities. "If my journey helps even one young Pacific person believe they belong in research, then the work is serving its purpose."

For NZ higher education, scholars like him signal a shift toward inclusive excellence. With rising Pacific enrollment (15 percent growth last decade), universities must invest in culturally responsive infrastructure—labs, scholarships, mentorship—to harness this talent for national health gains.

Challenges remain: funding cuts, brain drain, and equitable data access. Yet, with advocates like 'Atiola, the trajectory points upward, promising healthier futures for Pacific whānau through homegrown genetics expertise.
