I am senior lecturer at the School of Computer Science of the University of Auckland, CTO of enviPath, and lead the Machine Learning Group at UoA. My main research area is machine learning and its application to bioinformatics, cheminformatics, and computational sustainability. Before joining the University of Auckland in 2017, I did a PostDoc at University of Mainz, Germany, and a PhD at Technical University of Munich, Germany. I am always interested in interesting new research areas both for applied and non-applied machine learning, currently, I am particularly interest in reliability of machine learning algorithms, adversarial machine learning, and bias, with applications in chemistry, epidemiology, and environmental research.
My main research lies in the intersection of machine learning, meta-heuristic optimization, mathematical modeling, and data science with major applications in the filed of biology, ecology, engineering and social sciences. My work is strongly motivated by real-life problems that can benefit from data-driven modeling and automated modeling approaches exploiting both domain-specific knowledge and different types of measured data as relevant for systems sciences.
Postdocs
I am a Post Doctoral Fellow in the School of Computer Science participating in projects on green and sustainable computing, freshwater modeling, and ethical computing. My main research interests revolve around the reliability of data and models, particularly with respect to biases, adversarial learning, and active learning. I enjoy solving real-life problems that matter, especially in chemistry or environmental applications.
As Research Fellow at the School of Computer Science I am involved in the SHIVERS project, investigating influenza and respiratory diseases in a post-COVID world. This project will be driven by algorithms from machine learning and data mining which is in line with my previous research activities. I received my PhD at the University of Mainz, Germany before I joined the Emergent AI Center in Mainz to work on neuroscience-related data and to explore novel machine learning strategies. My main research track is based on large-scale sequencing data from molecular biology and I am interested in working with interpretable models.
PhD Students
I am currently pursuing a PhD from the Department of Computer Science, while working as a Senior Research Engineer at Callaghan Innovation. I have a Master of Engineering Management(Hons) and Bachelor of Computer Systems Engineering, both from University of Auckland. My research involves achieving robust semantic scene understanding through joint optimisation of SLAM and DCNNs.

I am a PhD student in Computer Science at the University of Auckland. My research focuses on adversarial learning on time series. The field of time series involves numerous vital applications such as stock market prediction, climate change investigation, energy consumption estimation, etc. Model robustness is always one of the biggest concerns in those crucial applications. In addition, adversarial learning could also provide insights into those models, which might potentially provide instructions on interventions required at the present in order to change the future.

My research is primarily in cheminformatics, investigating using machine learning to predict the outcomes of chemical reactions. This can help reduce the R&D time for novel chemicals that improve people’s lives, including drugs for disease treatment and fertilisers for reducing agricultural environmental impacts. In 2022 I completed my Bachelor of Advanced Science (Honours) at the University of Auckland, and in 2023 I am continuing my research as a PhD student.
I am also involved in a project as part of Predator Free NZ 2050 using machine learning to aid in reducing the predator population in New Zealand bush. I joined this project in November 2022 as a research assistant for Katerina Taskova, and I will be continuing this role part-time alongside my PhD.

I am a PhD student at The University of Auckland. I have a Master´s Degree in Artificial Intelligence from the Polytechnic University of Madrid, Spain, and a Combined Honours Degree in Software Engineering and Mathematics from the Rey Juan Carlos University in Madrid, Spain.
My PhD research is part of a SfTI project with the mission to eradicate New Zealand predators and pests by 2050. My main goal is to use Artificial Intelligence to make predator (rats, possums, mustelids, etc.) identification using Artificial Vision, Neural Networks and other Artificial Intelligence systems. As I am in my first year, I am currently looking for where to contribute to the Computer Science state of the art and inside the project.
My supervisors are Katerina Taskova and Gill Dobbie.
Influenza is a communicable respiratory illness that can cause serious public health hazards. Due to its huge threat to the community, accurate forecasting of Influenza-like-illness (ILI) can diminish the impact of an influenza season by enabling early public health interventions. Current forecasting models are limited in their performance, particularly when using a longer forecasting window. Commonly used methods to forecast ILI, including statistical methods such as ARIMA, limit prediction performance when using additional data sources that might have complex non-linear associations with ILI incidence. In my PhD, I use machine learning approaches to build models that can predict ILI cases more reliable further into the future.

I started my PhD journey at the School of Computer Science in 2022, working in the direction of opinion mining and text summarisation. My prior academic training included a second Bachelor’s degree in Science (mathematics and computer science) and a Master’s degree in organisational psychology from the University of Auckland. As a returned student, I have worked in the education, management consulting, and marketing research industries centred around process / system redesign as well as quantitative and qualitative methods and analyses. I am passionate about contributing to real-world problem-solving, especially in areas such as education, biodiversity, sustainability, and conservation. Outside my PhD topic, I have broad interests in both theoretical and applied inter-disciplinary topics that involve applied mathematics, modelling, quantitative and qualitative analytics.
