個人經歷


經歷

　　李健榮於民國98年獲得國立中山大學電機博士學位，他曾短暫於聯發科技公司射頻系統部門擔任資深工程師一職，後於100年轉任教於國立台北科技大學電子系。他於103年7月辭去助理教授一職，返回業界服務。

　　過去他曾擔任國際電子電機工程師協會 (IEEE) 數個國際會議與期刊論文 (T-MTT, T-CAS, Trans. Broadcasting 等) 之審稿委員、國際會議工作小組委員、教育部高速電磁教育推動工作小組委員、民航局航空電子講師、自強工業科學基金會專業講師、台北市捷運局試務命題與口試委員、美商安捷倫科技專業講師等服務性工作。至今他仍持續協助自強基金會開辦電機/資訊專業領域課程，經常與業界工程人員維持專業互動與經驗交流。

　　李博士的專業領域為微波工程、RF電路與系統設計以及數位輔助射頻技術等，長期投入無線通訊前端關鍵元件、低耗能通訊前端系統架構、晶片級電磁訊號干擾與防治、頻譜訊號感測以及非接觸式生醫訊號感測等研究。他的研究獨特之處在於整合射頻、類比與數位訊號處理技術，常以數位技術輔助或增強系統之性能。

　　他在學期間，曾於94年與實驗室團隊以「可應用於 DECT, GPRS及CDMA2000 之高效率多模發射機」實作奪得該年度全國大專校院通訊科技競賽研究所組特優獎。他於台北科技大學任教期間，曾於102年帶領學生以「無線智慧鑰匙系統」實作專題獲得該年度教育部技專校院技術研發成果發表記者會優勝獎。

　　自94年起，他共表發了十篇國際期刊論文以及近二十篇國際會議論文。在他所主筆的期刊代表性著作中，分別有兩篇為原創性與基礎理論型之研究，自民國98年起迄今已被國內外近五十篇文獻所引用，他的研究成果也被收錄於美國 John Wiley & Sons 所出版的「Microwave Noncontact Motion Sensing and Analysis」一書之中。他執行過包含國科會、教育部、工研院、中科院、飛元科技、科邑科技等橫跨產官學研近二十個計畫案。他擁有兩項中華民國發明專利(證書號：I380604, I388168)與一項美國發明專利(證書號: US8648611)。
