- Known for: Research in mathematics and cryptography, including a 1996 doctoral thesis on modular curves
- Employer(s): University of Auckland (from 2009); University of London (2002–2009); University of Bristol (2000–2001)
- Field(s): Mathematics, cryptography, computer science, university teaching

## Contributions
Steven Galbraith authored the doctoral thesis "Equations for modular curves" (1996) under the supervision of Bryan Birch. That thesis is a documented part of his academic output and ties to his work in number theory and cryptography. He has held academic positions at the University of Bristol (2000–2001), the University of London (2002–2009), and the University of Auckland (from 2009), where he has taught and supervised research. Galbraith has supervised at least ten doctoral students (including Jordi Pujolàs, Philip Nicholas James Eagle, David J. Mireles Morales, Waldyr Dias Benits Jr., Raminder Singh Ruprai, Edoardo Persichetti, Shishay Welay Gebregiyorgis, Barak Shani, Yan Bo Ti, and Shujie Cui), producing completed PhD theses referenced in institutional repositories. His work is indexed in major bibliographic and research databases (DBLP author id 77/5607; zbMATH galbraith.steven-d; Google Scholar author id m-FSAfgAAAAJ), and he maintains an academic website (https://www.math.auckland.ac.nz/~sgal018/). Recognitions tied to his research and teaching include the Aitken Lectureship (2015) and election as a Fellow of the New Zealand Mathematical Society.

## FAQs
### Q: Who is Steven Galbraith?
A: Steven Galbraith is a New Zealand mathematician and cryptographer who completed a DPhil at the University of Oxford in 1996 and holds a faculty position at the University of Auckland since 2009.

### Q: What is his main research area?
A: His documented research includes number theory related to modular curves, with a 1996 doctoral thesis titled "Equations for modular curves." He is identified professionally in mathematics and cryptography.

### Q: Has he supervised PhD students?

## Why They Matter
Steven Galbraith's significance rests on his contributions to mathematical research in areas connected to cryptography, his sustained academic appointments, and his role in doctoral training. His 1996 doctoral thesis, "Equations for modular curves," documents work in number theory that interfaces with cryptographic topics. Over a career spanning posts at the University of Bristol, the University of London, and the University of Auckland, Galbraith has taught, advised, and produced doctoral graduates who continued research in related fields. Recognition such as the Aitken Lectureship (2015) and fellowship of the New Zealand Mathematical Society reflect peer acknowledgment of his scholarly and pedagogical contributions. His publications are indexed across major bibliographic services (DBLP, zbMATH, Google Scholar), providing access and continuity for researchers building on his work. Without his teaching, supervision, and academic outputs, a body of doctoral research and lectureship-level dissemination in his areas of expertise would be diminished; his students and indexed publications help carry his influence forward.
