You could use the CellFormatting Event of the DataGridView.  Example:
Public Class Form1
	Private People As New List(Of Person)()

	Private Sub OnLoad(ByVal sender As Object, ByVal e As EventArgs) Handles MyBase.Load
		For i As Integer = 1 To 20
			People.Add(New Person() With {.ID = i, .Name = String.Format("Person{0}", i), .Role = If(i Mod 5 <> 0, "S", "I")})

		DataGridView1.DataSource = People
	End Sub

	Private Sub OnCellFormatting(ByVal sender As Object, ByVal e As DataGridViewCellFormattingEventArgs) Handles DataGridView1.CellFormatting
		If TypeOf sender Is DataGridView Then
			Dim grid As DataGridView = DirectCast(sender, DataGridView)
			If e.RowIndex <> -1 AndAlso Not String.IsNullOrEmpty(e.Value) Then
				If grid.Columns(e.ColumnIndex).DataPropertyName().Equals("Role") Then
					e.Value = If(e.Value.ToString().Equals("S"), "Student", "Instructor")
					e.FormattingApplied = True
				End If
			End If
		End If
	End Sub
End Class

Class Person
	Public Property ID() As Integer
	Public Property Name() As String
	Public Property Role() As Char
End Class
