AI Research Scientist Roadmap

From math and deep learning theory to paper reproduction, experimentation rigor, and novel model development — the structured, free path to becoming an AI research scientist.

8 learning stages
15+ free courses & tutorials
~1–1.5 yr full-time pace
01 —

Mathematical & Theoretical Foundations

6–8 weeks

The math that separates a research scientist from someone who calls `.fit()` — you need to derive it, not just use it.

What you'll learn

  • Linear algebra and vector calculus for deep learning
  • Probability, information theory, and entropy
  • Optimization theory: convexity, convergence, saddle points
  • Statistical learning theory basics (generalization, VC dimension)
02 —

Deep Learning Architectures & Theory

8–10 weeks

Derive backpropagation yourself, then understand why every major architecture decision exists.

What you'll learn

  • Backpropagation and gradient computation from first principles
  • CNNs, RNNs, and transformer architectures
  • Normalization, residual connections, and why they stabilize training
  • Vanishing and exploding gradients — causes and fixes
03 —

Optimization & Training Dynamics

4–6 weeks

Why training works, why it fails, and how to diagnose the difference — a core research-scientist skill.

What you'll learn

  • Gradient descent variants and stochastic optimization
  • Variance reduction techniques in SGD
  • Hyperparameter sensitivity and regularization theory
  • Diagnosing a training run: loss curves, gradient norms, learning rate schedules
04 —

Reading, Reproducing & Critiquing Papers

4–6 weeks

The unglamorous skill that determines whether you can actually build on prior work instead of reinventing it badly.

What you'll learn

  • Reading a paper efficiently: abstract → method → results → limitations
  • Reproducing a published result from scratch
  • Spotting weak baselines, cherry-picked results, and benchmark contamination
  • Maintaining a running literature map for your subfield
05 —

Experimentation & Evaluation Rigor

4–6 weeks

The discipline that separates a real research result from a lucky seed.

What you'll learn

  • Designing controlled ablations that isolate one variable at a time
  • Statistical significance and variance across random seeds
  • Avoiding evaluation leakage and overfitting to a benchmark
  • Reproducible experiment tracking and versioning
06 —

Novel Model Development & Adaptation

6–8 weeks

Turn theory into a contribution: fine-tune, adapt, and test new ideas against strong baselines.

What you'll learn

  • LoRA, QLoRA, and parameter-efficient fine-tuning (PEFT)
  • Designing and running architecture ablations
  • Agentic and RAG systems as research substrates
  • Prompt-based evaluation of new methods
07 —

Research Communication & Writing

3–4 weeks

A result nobody can read or trust does not advance the field — or your career.

What you'll learn

  • Writing a clear, reproducible methods section
  • Building result tables and figures that hold up to scrutiny
  • Responding to reviewer critique without getting defensive
  • Presenting a research result to non-research stakeholders
08 —

Interview Preparation

Ongoing

Prepare for a loop that tests theory depth, implementation skill, and research judgment — not just LeetCode.

What you'll learn

  • Presenting and defending your own past research
  • Whiteboard research ideation and open-ended critique
  • Implementing a method from a paper under time pressure
  • Explaining a failed experiment and what you learned from it
