<!-- # 현 Covid-19과 지난 MERS 사태는 21세기 들어서 대략 5년 간격으로 우리나라가 겪은 대규모 감염병 사태 (epidemic) 중 일부일 뿐입니다. 국제적으로도 Ebola나 Zika 등 감염병 사태가 점점 빈발하고 있습니다. 현재 감염병 대응은 IT 기술을 거의 사용하고 있지 않습니다. 우리 연구실은 감염병 대응에 있어 IT가 해 줄 수 있는 역할을 연구하고 있습니다. 특히 우리가 항상 휴대하는 모바일 기기를 이용하여 잠재적인 감염 상황을 감지하고 기록하는 연구를 하고 있습니다. 또한 social media와 Web을 사용한 infoveillance와 infodemiology를 연구합니다.
# 이 기술에 대한 관심 때문에 우리 연구실 국승호 학생의 논문은 Electronics Letters 2017년 1월과 9월 두 번에 걸쳐 featured article로 선정되기도 했습니다.
# 우리 연구실은 한국 연구재단의 지원으로 MERS, SARS, 신종플루와 같은 미래 감염병 응급 상황에서 필요한 IT 신기술을 연구하는 Smart Disease Detection 과제를 우수하게 수행한 바 있습니다.
# 우리 연구실은 2020년부터 2029년까지 10년 동안 디지털 트윈을 기반으로 방역 및 역학조사에 필수적인 IT 신기술을 연구합니다.-->
