# Researchers

## Ignacio Cascudo

### Associate professor

Cryptography, mainly in the areas of secure multiparty computation and secret sharing, and is especially interested in the applications of algebra, algebraic geometry and coding theory to those areas.

## Olav Geil

### Professor MSO

Affine variety and algebraic geometry codes. He studies their parameters, their decoding algorithms and their applications in secret sharing schemes.

Olav also takes an interest in multivariate polynomials over finite fields and in algebraic function field theory. Furthermore, he works on network coding.

## Tom Høholdt

### Adjunct professor

Algebraic coding theory, sequence design, signal analysis and other areas of applied (discrete) mathematics.

## Umberto Martínez-Peñas

### Research assistant

Algebra, algebraic geometry and sum-rank codes, and their applications to network coding, secret sharing and distributed storage.

## Ryutaroh Matsumoto

### Adjunct professor

Network coding, algebraic ccoding theory, quantum communication.

Ryutaroh is currently working at Nagoya University.

## Diego Ruano

### Associate professor

Algebraic coding theory, which includes aspects of algebraic function fields, algebraic geometry codes and decoding algorithms.

Diego also studies code-based cryptography, secret sharing and network coding. He is currently a ‘Ramón y Cajal’-fellow at the University of Valladolid.

# Former members
