Ya koyar a sashen lissafi har zuwa 1947 kuma ya shiga sashen injiniyan sinadarai na Jami'ar Minnesota, inda ya yi aiki a matsayin Shugaba daga 1949 zuwa 1977. A cikin shekaru 25 da ya yi yana shugaban sashen, Amundson ya taimaka wa sashen don samun babban matsayi a ƙasa a tsakanin sassan injiniyan sinadarai, wanda har yanzu yana nan. 

Amundson ya shiga Jami'ar Houston (UH) a shekarar 1977 a matsayin Farfesa Cullen kuma memba na sashen Injiniyan Sinadarai da Lissafi. Ya yi aiki a matsayin Provost na UH daga 1987 zuwa 1989. An san Amundson a duniya saboda aikinsa na farko wajen amfani da ƙirar lissafi da bincike don magance matsalolin injiniyan sinadarai. Gudummawar da ya bayar ta fasaha ta shafi fannoni na ƙirar lissafi da nazarin na'urorin sinadarai, tsarin rabuwa, na'urorin polymerization, da na'urorin gas na kwal.  Amundson yana ɗaya daga cikin manyan masu tsara hanyoyin nazari da injiniyoyin sinadarai ke amfani da su a yau. 

Amundson ya rubuta kasidu sama da 200 na fasaha da kuma littattafai da dama. Ya jagoranci kwamitin Majalisar Bincike ta Ƙasa ta Amurka wanda ya rubuta rahoton "Frontiers in Chemical Engineering". Shi ne editan Amurka na Kimiyyar Injiniyan Sinadarai daga 1955 zuwa 1972. An zaɓi Amundson a matsayin memba na Kwalejin Injiniya ta Ƙasa a 1970  da Kwalejin Kimiyya ta Ƙasa a 1992.  An zaɓe shi a matsayin Fellow na Kwalejin Fasaha da Kimiyya ta Amurka a 1992.  Kwalejin Injiniya ta Ƙasa (NAE) ta ba wa Amundson lambar yabo mai daraja ta waɗanda suka kafa NAE a 1990. 

A shekarar 1996, Amundson shi ne wanda ya fara cin kyautar International Symposia on Chemical Reaction Engineering (ISCRE) saboda kyakkyawan aiki,  kyautar da aka sanya masa suna. An sanya wa ginin injiniyan sinadarai a Jami'ar Minnesota sunansa don girmama shi.  Ya sami kyaututtuka da yawa na ƙwararru daga Cibiyar Injiniyan Sinadarai ta Amurka (AIChE), Ƙungiyar Sinadarai ta Amurka (ACS), Taron Ƙasa da Ƙasa kan Injiniyan Sinadarai (ISCRE), da Ƙungiyar Ilimi ta Injiniya ta Amurka (ASEE).
