Documented path
Born in India, Sudan earned his bachelor's from IIT Delhi in 1987 and his PhD from UC Berkeley in 1992 at age 26 under Umesh Vazirani.
Born in India; family background not documented.
Gordon McKay Professor at Harvard University; Nevanlinna Prize laureate (2002).
Where the conditions came from
Each is placed on a −1 to 3 scale from documented evidence, and the three are never added together. A combined total would rank Madhu Sudan against other people. Held apart, they explain why this path ran differently from another one—which is the only comparison this project supports.
The marble itself
+1Tailwind
What capability, drive, or early skill is documented in the person rather than their surroundings?
IIT Delhi bachelor's, Berkeley PhD at 26. Nevanlinna Prize winner. Good academic trajectory but no specific prodigy-level early evidence or competition achievements found.
Where it was dropped
0Neither way
What money, family standing, network, or permission was already in place before the work began?
Born in Madras (Chennai), India. No evidence of special family background, wealth, or academic connections. Ordinary Indian family.
The shape of the track
+2Tailwind
What place, timing, institution, or peer group made the next step available?
IIT Delhi (elite Indian engineering institution), Berkeley PhD under Umesh Vazirani. The IIT-to-Berkeley pipeline in theoretical computer science was strong, same advisor as Arora.
A −1 is a documented headwind, not a missing value; a 0 means the sources record nothing notable either way. Annotation confidence: Medium. These are analyst readings of what the sources record, not measurements of merit, talent, or effort. The twenty-two scored dimensions remain available inside the deeper research detail.
What moved through the conditions
Silence in a biography is not evidence that perseverance was absent.
A successful-only archive cannot recover all encounters, avoided setbacks, or alternative outcomes.
Strongest documented signals: Elite institution pipeline, Frontier geography, Dedicated mentor / coach.
Describes the starting position, not what the person later made of it.
Strongest observed levers: Scarce skill depth, Domain proximity, Started serious reps before 20.
Measures what was present, not whether it was inherited, earned, self-built, external, or mixed.
The timeline below shows the sequence of work and transitions around the selected early milestone. It is evidence of a path, not proof that every step was necessary.
Legendary or globally iconic career standing. The tier summarizes documented career recognition through the data cutoff—not Madhu Sudan's worth or future potential.
Question four · where did the leverage come from?
Each non-zero lever gets a best-supported origin, evidence signals, and confidence. Unresolved is the honest default when the biography cannot distinguish self-built, advantage-enabled, earned, external, or mixed.
One or more documented starting advantages plausibly enabled this lever.

A structural wave is external to the person, even when their position improved access to it.
This is a bounded inference from the current annotations—not a claim about private effort, merit, or the percentage of Madhu Sudan's outcome attributable to any origin.
Structural luck, Encounter luck, Event luck, Outcome variance can change every arrow in the path. This successful-only dataset cannot observe the near-identical paths that did not break through, so luck stays visible and unscored.
Multiplying capacity documented later in the path. Measures what was present, not whether it was inherited, earned, self-built, external, or mixed.
Access or conditions documented near the beginning of the path. Zero means "no clear evidence in reviewed sources," not "advantage was absent."
Born in India; family background not detailed.
Not documented in reviewed sources.
Sudan completed his bachelor's at IIT Delhi in 1987 and PhD at UC Berkeley in 1992 at age 26 under Umesh Vazirani. He won the Nevanlinna Prize in 2002.
