Born where the road ends. Working so help doesn't.

A public health physician and Health Officer at UNICEF Bangladesh, leading national work on lead poisoning, climate and health, and health emergencies. One goal runs through all of it: a child's birthplace should never decide whether that child gets care.

A decade with
UNICEF World Health Organization Gavi, the Vaccine Alliance Save the Children Government of Bangladesh, MoHFW and DGHS

01  It started with the water

He grew up in a coastal district that rivers and sea had cut off from the rest of Bangladesh. There was no road out. Floods came without warning. Cyclones redrew villages overnight. Mothers and children died. The medicine existed. It just couldn't get there. He has spent every year since [closing that distance.]

03  The journey

From the ward to the national table.

Seven chapters. Each one moved him a step further from treating a single patient and a step closer to fixing why patients get sick.

The doctor

MBBS, Sher-e-Bangla Medical College · Honorary Medical Officer, Dhaka Medical College & Hospital

He trained to treat one patient at a time. The wards taught him what textbooks skip: by the time a child reaches the bed, the real story started long before.

Early career

Back to the coast

District MCH & Immunization Officer · MoHFW, Gavi Health Systems Strengthening

Maternal, child and immunization programmes in remote coastal areas. Public health learned from the ground, not from a policy paper.

2017

The standard

Divisional Quality Improvement Coordinator · Save the Children Bangladesh

A short posting with a long reach: asking whether care across a whole division was actually good, not just available.

2017 / 21

The doorstep

Surveillance & Immunization Medical Officer · World Health Organization

Cox's Bazar during the Rohingya influx: early warning systems and the world's largest oral cholera vaccine campaign. Then Bhola, from 63rd to 1st.

2021

The advocate

Health Affairs Secretary · Legal Aid Center Foundation (ASK)

A brief role bringing a physician's view to legal aid and rights work, before UNICEF called.

The frontline division

Health Officer · UNICEF Barishal Field Office

Maternal, newborn, child and adolescent health and climate resilience in one of the most climate-exposed divisions in the country.

Now

The system

Health Officer · UNICEF Bangladesh Country Office, Dhaka · Since 2023

Three pillars, one country: Environmental Health, Climate Change and Health, and Health Emergency Preparedness and Response. Working with DGHS, ministries and partners.

04  In his words

“The question was never how to treat one sick child. It was [why so many children get sick] in the first place.”

Dr. Hasnain Ahmed

Three fronts. Every day.

05  The work at UNICEF Bangladesh, where evidence becomes national policy

01

Lead, the quiet poison.

Environmental health

Bangladesh had no national lead strategy, no coordination and no lab capacity for heavy metals. Millions of children were being harmed and almost nobody was looking. He made the country look.

40%of children tested in the 2022 pilot were above the WHO reference level
13,707blood and 11,529 soil samples in the first national lead survey
