Technical Presentation versus Other PresentationsTechnical Presentation You do all the talking until someone asks a questionDelivering scientific resultsCan have personality but should maintain a degree of professionalismPowerPointChurch PresentationUsually do a fraction of talking (5% R.S.; 10% priesthood)Include stories, feelings, personal experiencesMore personableYou ask the questionsPowerPoint Presentation GuidelinesCant Go WrongAvoidBackgroundPlain WhiteDistracting backgrounds

Videos and AnimationCan be extremely effectiveEmbed and make sure its bulletproofDont leave video looping

Technical ContentBackgroundAdjust to your audienceWhat do you need to know to understand significance of what Im talking aboutWhy should you careWhy what Im doing is so great

Background slides could range from 1 to most of the talk depending on your audienceTechnical ContentThings people like Big picturesSummaryResultsNew StuffSimple explanationsThings people dont likeThinking too hardGory detailsRepetitionEndless equationsMeaningless informationEndless talkingMental state of most audience members: sleepy, lethargic, bored, distracted, defensiveThe Act of PresentingTry to be natural lots of eye contactDont read slidesDont over/under prepareDont over/under explainDont go crazy with the laser pointer

Acting Natural, Lots of Eye ContactExample

4) End Coupling of Solid and Hollow Core Waveguides3) Intersection of Solid and Hollow Core Waveguides5) Integration of Macroscopic Fluid Reservoirs2) Bends and Intersections of Fluid Channels1) Hollow Core WaveguidesIntegrating Microfluidics and Hollow WaveguidesDont Read SlidesExampleSIM Key to the OperationElectrons created during ionization are collected at N+ region.

Holes created during ionization are directed towards the P+ substrate instead of back towards the current sourceavoid carrier recombination and gain suppression
