Starting SofiaMind
Published:
Starting a company has always been a dream of mine, and in September 2023, I co-founded SofiaMind with a few talented students at University of Tehran. Our vision was to create intelligent chatbots leveraging state-of-the-art AI technologies such as large language models (LLMs) and retrieval-augmented generation (RAG).
Research Assistantship at Columbia University
Published:
Starting in January 2024, I joined Columbia University as a remote Research Assistant under the mentorship of Dr. Maryam Zolnoori. Our research focuses on leveraging large language models (LLMs) for clinical decision support, with the ultimate goal of developing real-time diagnostic tools for healthcare.
Joining OptiGrid
Published:
In January 2024, I began working remotely with OptiGrid Pty Ltd, an Australian company focused on energy optimization solutions. My role involves building APIs for data-driven decision-making and performing data analysis and modeling to enhance system efficiency.
Research Assistantship at Nottingham Trent University
Published:
In March 2024, I joined Nottingham Trent University as a remote Research Assistant, working under the guidance of David Brown, Mufti Mahmud, Alexander Sumich, and Nadja Heym. Our project involves conducting a systematic review of deep learning approaches on EEG data for the early detection of Alzheimer’s Disease and Mild Cognitive Impairment (MCI).
SofiaMind’s First Client
Published:
A significant milestone for SofiaMind was securing our first major client, the University of Tehran, in March 2024. We successfully deployed a chatbot system to handle various university services, from answering student inquiries to assisting with administrative tasks.
