Research Experience


OxyJet CPAP – A Low Cost, Electricity free, Noninvasive Ventilation Device
Supervisor: Dr. Taufiq Hasan, Associate Professor, Department of BME, BUET.

  • OxyJet CPAP has been developed to support hypoxemic patient outside critical care. During the COVID-19 pandemic, it was developed to address the severe shortage of ICUs and to provide higher-level respiratory support in general wards or resource-limited settings.
  • OxyJet was acknowledged in the 2022 publication “Good Practices in South-South and Triangular Cooperation” by the United Nations Office for South-South Cooperation (UNOSSC).
  • On July 28, 2021, the device received limited approval for hospital by the Directorate General of Drug Administration (DGDA), the medical device regulatory authority of Bangladesh.

Deep Learning-Based Decoding of Motor Imagery for Practical Brain-Computer Interfaces
Supervisor: Dr. Muhammad Abdullah Arafat, Assistant Professor, Department of EEE, BUET.

  • Developed an AI based algorithm to detect sleep apnea and motor imagery classification from EEG signals.

Clinical Trials:

OxyJet CPAP April 2023 – July 2023
Supervisor: Dr. Taufiq Hasan, Associate Professor, Department of BME, BUET.

  • A randomized controlled trial was performed from April 17 to July 9, 2021, on 45 severely hypoxemic COVID-19 patients, between the OxyJet CPAP and the conventional high-flow nasal cannula, in Dhaka Medical College Hospital, Dhaka, Bangladesh (, NCT04681859).
  • OxyJet CPAP demonstrated comparable outcomes to high-flow nasal cannula treatment in supporting hypoxemic COVID-19 patients in general wards/pre-ICU settings.

Smile-Geist: Surgical Guide for Dental Implant Ongoing
Supervisor: Md. Kawsar Ahmed, Lecturer, Department of BME, BUET. Aug 2023 – Mar 2024 (Expected)

  • This project introduces patient-centered surgical guide-assisted dental implant surgery for the very first time in Bangladesh, aiming to advance digitalized dental care.
  • A randomized controlled trial is ongoing from August 2023, on 28 patients, to compare the accuracy between surgical guide assisted full-guided with free-hand dental implant surgeries, in Dhaka Dental College Hospital, Dhaka, Bangladesh (, NCT05983718).

Honors and Awards

  • 1st runner-up in Global Health, Johns Hopkins Healthcare Design Competition: “Smile-Geist: Surgical Guide for Dental Implant” (2023).
  •  Winner in Bangabandhu Innovation Grant (BIG) “OxyJet: A low-cost electricity-free CPAP for ICU Prevention of COVID-19 Patients” (2021).
  • Winner in Biomedical Engineering Society (BMES) Medtronic Student Design Competition for “OxyJet” (2021).
  • Global Winner of IMAGINE IF! – Innovation Forum (UK) for “OxyJet” (2021).
  • Winner of IDEA – Startup Bangladesh for “OxyJet” (2020).
  • Champion in IEEE Young Professionals Idea Contest: “To Mitigate Post-COVID Impact in Low- and Middle- Income Countries” (2020).
  • Winner in National Hackathon, organized by the Ministry of ICT, Bangladesh (2016).
  • Champion in the Industrial Automation Challenge, organized by Robotics Society of BUET (2016).
  • Secured Dean’s List Scholarship in all academic Levels of Undergraduate study.
  • Secured University Merit Scholarship in academic terms (2018, 2019) of Undergraduate study.
