About Me

I'm Negin, a last-year PhD candidate at the Data Science section of the Institute for Computing and Information Sciences at Radboud University. Currently, my main research focus is on enhancing neural information retrieval rankers, especially for federated search engines and low-resource datasets using LLMs.

Prior to starting my PhD, I was working on my master thesis as I was a Researcher at NLP Lab. I was also a Back-End Developer at Adanic, where I worked on the Kariz project. I completed my MSc and BSc at Department of Computer Engineering at Amirkabir University of Technology (Tehran Polytechnic).

Experiences

Phd Candidate - Informagus - Radboud University (2020 - Present)

My main research focuses on neural information retrieval rankers, with a particular emphasis on applications for federated search engines and datasets with limited resources. I dedicate my efforts to analyzing and enhancing transformer-based document rankers to use them in real-world applications. Following this path, I designed and implemented an app selection engine that leverages these advanced rankers. Currently, I'm designing cross-market question-answering and multi-resource systems and exploring the potential of automatic labeling for product question answering, using the capabilities of OpenAI and open-source Large Language Models (LLMs).

Researcher - NLP Lab - Amirkabir University of Technology (2016 - 2020)

I worked on different aspects of Information Retrieval and Natural Language Processing under the supervision of Dr. Saeedeh Momtazi. My research included improving a collaborative recommender system by using different user profiling, also developing an expert finding system using graph embeddings and text representation profiling, proposing a new model to represent users according to their past questions and answers.

Software Engineer - Adanic (2017 - 2020)

I worked as a Java Developer on a Channel Manager System named Kariz, which uses Java Spring Integration. This system makes an easy and effective management procedure of various channels, and it provides a uniform layer of all services. I also designed a monitoring system using elastic search, logstash, and kibana.

Intern - AtiNegar (2016)

      I was assigned to design an Investment Company Portfolio Management System as my summer internship project.        I used Python to carry out some statistical analysis and implement the "Efficient Frontier" algorithm.
