Exploring the developing brain.

I study how early-life exposures, brain development, genetics, and experience shape neurodevelopmental vulnerability and resilience—from the neonatal period through adolescence.

About me

Research with a focus on early life.

I am a postdoctoral researcher in Professor Ulrika Åden’s group at Karolinska Institutet. My research combines neonatal and childhood MRI, longitudinal developmental assessments, genetic epidemiology, and population-based cohorts to understand why children with similar early-life risks can follow very different developmental trajectories. My work spans extreme prematurity, neonatal hypoglycaemia, maternal cardiometabolic exposures, ADHD, autism, and digital media.

Research areas

A connected research programme.

From neonatal brain health to ADHD, autism, and opportunities for earlier intervention.

Preterm birth & early development

Studying gestational age, neonatal morbidities, cognitive and motor profiles, and variation in outcomes among children born preterm.

Developmental neuroimaging

Investigating cortical folding, brain networks, neonatal hypoglycaemia, and MRI markers linked to later development.

Digital media & mental health

Examining digital media activities, genetic susceptibility, ADHD symptoms, and brain development in longitudinal cohorts.

Maternal health & genetic risk

Exploring prenatal cardiometabolic exposures, genetic liability, and their associations with offspring brain structure, ADHD, and autism-related outcomes.

ADHD & autism heterogeneity

Investigating developmental pathways, brain imaging phenotypes, and why neurodevelopmental outcomes vary among children with similar early-life risks.

Physiological regulation & resilience

Developing research on neonatal physiological trajectories, early brain markers, and potentially modifiable influences such as skin-to-skin contact.

Interventions & early support

From risk identification to better support.

Research on interventions, modifiable exposures, and developmentally informed approaches to early support.

Published trial · 2026

Strength-based intervention after extremely preterm birth

I contributed to a randomized controlled trial evaluating a strength-based intervention for children born extremely preterm. At the assessed follow-up, the trial did not demonstrate improved neurodevelopmental outcomes compared with the control group. This informs how interventions should be evaluated and refined.

Research direction · neonatal period

Skin-to-skin contact & physiological maturation

My proposed research examines neonatal physiological regulation and skin-to-skin contact as a potentially modifiable influence on maturation. The aim is to investigate associations with early brain development and later neurodevelopment—not to assume a proven intervention effect.

Research direction · ADHD

ADHD risk identification & targeted support

My research investigates genetic, prenatal, and environmental factors associated with ADHD-related outcomes. These findings may help inform earlier identification and future targeted support strategies; they do not establish the effectiveness of a specific ADHD intervention.

Contributions to science

Research across five themes.

Key areas described in my research statement, connecting methods and questions across developmental stages.

01 · Neonatal brain health

Neonatal hypoglycaemia & later brain development

MRI studies examining neonatal hypoglycaemia, deep grey-matter differences, and later neurodevelopmental outcomes.

02 · Prematurity

Preterm birth & developmental heterogeneity

Registry and cohort research on gestational age, cognitive outcomes, brain networks, and neonatal morbidity.

03 · Prenatal exposures

Maternal cardiometabolic risk, ASD & ADHD

Studies of maternal diabetes, hypertension, BMI, brain structure, and offspring neurodevelopment.

04 · Childhood environments

Digital media, brain development & inattention

Longitudinal analyses distinguishing social media, television, and gaming; associations should not be interpreted as proof of causation.

05 · Autism neuroimaging

Brain metabolism & corpus callosum development

Exploratory PET and MRI work examining regional metabolic and structural patterns in children with autism.

Early lifeBrainOutcomes
Research perspective

From early markers to meaningful outcomes.

My work brings together neonatal neuroimaging, developmental neuroscience, genetics, and epidemiology to identify early markers and potentially modifiable pathways.

  • Perinatal factors: maternal health, gestational age, and neonatal exposures.
  • Brain measures: MRI markers of structure and development.
  • Long-term outcomes: cognition, motor function, attention, and mental health.
Background & engagement

Across disciplines and research settings.

My academic path has included research in perinatal neurology, neuroimaging, genetic epidemiology, cognitive neuroscience, and child development. Alongside research, I contribute to supervision, teaching, editorial and peer-review activities, and public communication.

I have also contributed to a European Commission scientific perspective on minors’ health and social media, and participated in international scientific and policy discussions.
