Clinical researcher · Heidelberg

Hi, I’m Mengmeng.

I ask clinical questions, annoy datasets until they answer, and occasionally recruit AI agents to help.

Clinical Medicine × Psychosomatic Medicine × Mental Health × Pain × Scientific AI

I like new knowledge, new places, new challenges, and—apparently—new notebooks.

Clinically trained across medicine, psychiatry and psychosomatic medicine, I work at the intersection of human health, complex data and scientific AI.

I am particularly interested in turning strong clinical datasets into testable questions, interpretable models and reusable research systems.

Currently in Heidelberg. Frequently found somewhere between a clinical question and a Python terminal.

THE OPERATING SYSTEM

How my brain works, approximately.

I tend to work on several questions in parallel. Switching between problems often helps me see connections I would miss if I stayed inside one project for too long.

Multitasking? Maybe. Parallel processing sounds more academic.

Mengmeng calmly inspects a hand-built control room inside a brain silhouette, where seven research tasks run on paper conveyors and an overfilled memory drawer spills notes.
Working memory questionable. Seems fine.
Three panels show Mengmeng working, noticing a comet-like new method, map and question, and immediately following it with notebook in hand.
NEW THING → investigate immediately
I enjoy research most when a problem requires me to learn something I did not already know.

A crooked academic path

  1. 01Clinical MedicineHumans are complicated.
  2. 02Psychiatry & Mental HealthHumans are REALLY complicated.
  3. 03Psychosomatic Medicine & PainApparently the body also has opinions.
  4. 04Causal Inference / Data Science / MLNeed better tools.
  5. 05LLMs / Agents / Scientific AINeed tools for the tools.

The topic changes. The habit does not: I like finding relationships, structures and logic between things that initially look unrelated.

ONE QUESTION, MANY WINDOWS

So what do I actually study?

Why can similar biological or psychological experiences become very different symptoms, behaviours and healthcare needs in different people?

Conceptual relationships, not unsupported causal claims.

RESEARCH WORLD

Pain is more than a number.

I study chronic pain as a heterogeneous, multidimensional human experience shaped by adversity, distress, perception, coping and functional burden.

Two panels contrast a patient respectfully describing pain with sleep, stress, movement and emotion around her, against a smiling clipboard reducing everything to one scale.
Patient: ‘It’s complicated.’ Questionnaire: ‘From 0 to 10?’

Pain: multidimensional. Dataset: also multidimensional. My RAM: less multidimensional.

RESEARCH WORLD

Adolescents do not live inside regression models.

Adolescent mental health unfolds across young people, parents, families, schools and pathways to help.

RESEARCH WORLD

Same symptom. Different meaning. Different care.

Is the health that medicine measures always the same as the health that people experience? Interviews, scales and clinical-entry data each reveal only part of the picture.

Three women appear within rich contexts of work, caregiving, relationships, sleep and symptoms while a clinical measurement frame captures only selected fragments; Mengmeng takes interview notes.
Measurement is also a point of view.

absence of medicalization ≠ absence of suffering

And then I started asking questions about science itself.

Can scientific work itself be redesigned? That question eventually led me to agents, reusable workflows and the Research OS.

AND HARD DRIVE

Things currently living on my desk.

Mengmeng reaches across a desk covered by five illustrated project notebooks while three new blank notebooks appear beside a version-control laptop.
Analog version control. Git was not enough.

SKETCHBOOK PAGES

Side quests & accidental adventures

Research has occasionally taken me places. European railways have occasionally taken me somewhere else.

Three panels show Mengmeng enjoying a European train, unexpectedly ending at an unfamiliar small station, then already exploring the town with suitcase, map, camera and a snack.
‘This train terminates here.’ ‘So do my plans, apparently.’

I love travelling. European railways have occasionally interpreted this as a collaborative decision-making process. Several trips ended somewhere I did not intend to visit. I generally visited it anyway.

A VERY SHORT LAB CAREER

My experimental biology career was brief.

During my first cell-biology practical, I somehow managed to kill the entire class’s cells.

I subsequently developed a healthy respect for people who can keep cells alive.

Mengmeng holds a pipette and looks sheepish beside a clean cell-culture dish containing several tiny paper gravestones, with a microscope and tubes nearby.
‘This may explain the career pivot.’

Here is a puzzle instead.

SCIENTIFIC AI, WITH SUPERVISION

Why I keep building new tools

I dislike repeating tasks that a machine could reasonably learn to do.

Not because repetitive work is beneath me. Because every hour spent renaming files, checking the same formatting rule, rebuilding the same literature table or retracing an old analysis is an hour not spent asking a better question.

How much of scientific work can be made reusable, auditable and modular—without outsourcing scientific judgment?
Three panels show Mengmeng asking for five papers, a tiny agent dragging a mountain of papers, and an even larger cart while Mengmeng looks silently at the viewer.
‘I found 327.’ ‘Would you like 812 more?’

RESEARCH OS

A workshop, not an autonomous scientist.

Raw data → audit → hypotheses → literature → analysis → comparison → figures → manuscript → review → provenance. The path loops whenever reality disagrees.

A large scientific workshop has stations for data, hypotheses, literature, analysis, figures, writing and audit; tiny agents carry folders along looping paths while Mengmeng makes decisions at the central whiteboard.
Modular. Iterative. Auditable. Human-supervised.

HUMAN JUDGMENT stays in the loop.

PROOF, NOT BUZZWORDS

AI, but what have you actually built?

Two-panel colored-pencil comic: Mengmeng crosses out a cloud of AI, LLM, Agent, RAG and ML labels, then supervises a concrete scientific AI architecture with a knowledge base, retriever, agent, evaluator, rule gate, human decision desk, audit ledger and version drawers.

What I ultimately want to build

Where all of this is going

Highly developed medical systems contain specialist expertise, clinical workflows, accumulated experience, decision structures, training systems, data and technology. These cannot simply be copied into remote or resource-limited settings.

Can we distill advanced medical knowledge, workflows and decision support into forms that can travel?
A serious panoramic illustration connects a complex medical ecosystem to a collaborative translation table and onward to confident local clinicians who adapt, teach and own their healthcare system, with feedback flowing both ways.
Knowledge transfer, adaptation and local ownership—not charity.

My long-term dream is to help make good medicine less dependent on postcode.

Especially in psychiatry.

Questions I would happily lose sleep over

01How can large clinical cohorts become discovery engines rather than paper factories?

02Can AI agents help scientists generate and falsify hypotheses systematically?

03How do psychosocial experiences become measurable biological or clinical burden?

04Why do medical systems see some symptoms clearly and barely see others?

05Can we connect pain, mental health, neuroinflammation and brain health using multimodal longitudinal data?

06What happens when medicine, causal inference and Scientific AI are designed together from the beginning?

07

Probably enough projects.

COLLABORATION

Got data? Got a weird question?

I am particularly interested in collaborations where the clinical question comes first and the method is allowed to evolve.

I am also interested in teams with strong clinical data that are beginning to build their AI / computational research capability.

ESPECIALLY INTERESTED IN

  • Large clinical cohorts
  • Longitudinal and multimodal health data
  • Pain / mental health / brain health
  • Scientific AI and AI-enabled clinical research
  • Human–AI research workflows
